Define _POSIX_C_SOURCE to be 200112L, as a minimum for C99.

Strict platforms cannot be expected to accept C99 code as valid when earlier standards versions are selected. This helps the programs build on Solaris-like platforms (e.g. illumos). Fixes Mbed-TLS#3420 Signed-off-by: nia <[email protected]>
