libgfortran: Verify the presence of all functions for POSIX 2008 locale
While we have `configure' checks for the individual POSIX 2008 extended
locale functions we refer to and use to guard the respective call sites,
we only verify the presence of `newlocale' for our global feature enable
check. Consequently compilation fails for targets like NetBSD that only
have partial support for POSIX 2008 locale features and in particular
lack the `uselocale' function:

make[3]: *** [Makefile:6221: transfer.lo] Error 1
Only enable the use of POSIX 2008 extended locale features then when all
the three functions required are present, removing said build errors.
