Remove testsuite.test for leanTLS builds

[miyazakh]

Fix: Skip testsuite/testsuite.test for --enable-leantls builds

Problem

When configuring with --enable-leantls, running make check causes
testsuite/testsuite.test to crash with a segmentation fault (exit code 139)
before main() is ever reached.

Root Cause

The leantls configuration adds -fvisibility=hidden (via the standard
wolfSSL visibility check) together with -DNO_WOLFSSL_SERVER and other
stripping flags. On macOS, this combination causes Apple's linker to set
LC_MAIN.entryoff = 0 in the resulting Mach-O binary — pointing the
OS entry-point dispatcher at the Mach-O header itself rather than at the
main() function. When dyld hands control to offset 0, the CPU tries to
execute the magic bytes 0xCF 0xFA 0xED 0xFE as x86-64 instructions;
0xCF is the privileged iret opcode, which immediately raises a
General Protection Fault in user space.

LC_MAIN:
    entryoff = 0   ← should point to main(), not the Mach-O header

This is confirmed by the crash report:

Exception: EXC_BAD_ACCESS (EXC_I386_GPFLT)
Frame:     imageOffset=0, imageIndex=0  (testsuite/.libs/testsuite.test)

Even though _main exists in the binary at the correct address, the
incorrect entryoff value prevents it from ever being called. The crash
is reproducible on macOS (Apple Silicon via Rosetta) on the unmodified
master branch; it is a build-system issue unrelated to any logic change.

Why the test is meaningless with leantls

Even if the binary were not crashing, testsuite/testsuite.test would
perform no useful work under --enable-leantls: the entire test body in
testsuite/testsuite.c is guarded by

#if !defined(NO_WOLFSSL_SERVER) && !defined(NO_WOLFSSL_CLIENT) && \
    !defined(NO_TLS) && ...

and leantls defines -DNO_WOLFSSL_SERVER, so the function returns
EXIT_SUCCESS immediately without executing any TLS tests.

Fix

testsuite/include.am

Replace the BUILD_TESTS conditional with BUILD_EXAMPLE_SERVERS.
BUILD_EXAMPLE_SERVERS is already defined in configure.ac as:

AM_CONDITIONAL([BUILD_EXAMPLE_SERVERS],
    [test "x$ENABLED_EXAMPLES" = "xyes" &&
     test "x$ENABLED_LEANTLS"  = "xno"])

This prevents testsuite/testsuite.test from being built or added to
the check_PROGRAMS list when leantls is enabled, eliminating both the
crash and the pointless build overhead.

Makefile.am

The existing rules

tests/unit.log:   testsuite/testsuite.log
scripts/unit.log: testsuite/testsuite.log

order tests/unit.test and scripts/unit.test to run only after the
testsuite finishes. Without this guard they would become unsatisfied
dependencies whenever testsuite/testsuite.test is absent from the
build. The rules are conditioned with the automake @COND_TRUE@ syntax:

@BUILD_EXAMPLE_SERVERS_TRUE@tests/unit.log:   testsuite/testsuite.log
@BUILD_EXAMPLE_SERVERS_TRUE@scripts/unit.log: testsuite/testsuite.log

so they are emitted into the generated Makefile only when server
examples (and thus the testsuite) are actually built.

Pull request overview

This PR adjusts the autotools build rules so testsuite/testsuite.test is not built (and therefore not run during make check) when configuring with --enable-leantls, avoiding a macOS-specific crash and skipping a test binary that would be effectively inert under leanTLS.

Changes:

• Gate testsuite/testsuite.test behind BUILD_EXAMPLE_SERVERS (which is false for leanTLS) instead of BUILD_TESTS.
• Conditionalize tests/unit.log and scripts/unit.log ordering rules so they are only emitted when the testsuite target exists.

File	Description
testsuite/include.am	Switch testsuite build conditional to BUILD_EXAMPLE_SERVERS to exclude leanTLS builds.
Makefile.am	Emit log-ordering dependencies only when BUILD_EXAMPLE_SERVERS is true, preventing missing-dependency errors when testsuite is absent.
