[Bug libfortran/21185] libgfortran unusable for cross-testing for newlib targets

Sorry, build fails for cris-elf with:

Besides the obvious s/amod/amode/ typo, maybe use a different name for the
internal function, and
#ifndef HAVE_ACCESS
... libgfortran_access implementation
#else
#define libgfortran_access access
#endif
to avoid problems with the access prototype.

I'm testing such an updated patch.
