Revert "Make libc symbols hidden in static PIE" [BZ #27237]

Browse Source 
This reverts commit 2682695e5c.
Fixes bug 27237.

That commit turned out to be too intrusive affecting crt files, test
system and benchmark files.  They should not be affected, but the
build system does not set the MODULE_NAME and LIBC_NONSHARED reliably.
