3.4 PATCH: Fix Tru64 UNIX V4.0F bootstrap failure

- Subject: 3.4 PATCH: Fix Tru64 UNIX V4.0F bootstrap failure
Current mainline failed to bootstrap on alpha-dec-osf4.0f:
/vol/gnu/src/gcc/gcc/gcc/ggc-common.c: In function `gt_pch_save':
/vol/gnu/src/gcc/gcc/gcc/ggc-common.c:460: warning: comparison between pointer and integer
/vol/gnu/src/gcc/gcc/gcc/ggc-common.c: In function `gt_pch_restore':
/vol/gnu/src/gcc/gcc/gcc/ggc-common.c:612: warning: comparison between pointer and integer
This happens because (unlike Tru64 UNIX V5.1), <sys/mman.h> defines
#define MAP_FAILED (-1L) /* unsuccessful return from mmap() */
The following patch fixes this and allows the bootstrap to continue.
Ok for mainline if it passes?

(gt_pch_restore): Likewise.
