linux(uclibc): move definition of time_t

A recent patch [1] overhauled the `uclibc` module to add support for
"toggling" 64-bit `time_t`. That patch, though, was centered around
supported 32-bit arm targets.

This patch extends that to all platforms whose target environment
matches `uclibc`. This option is mahine word-independent.
