Adhemerval Zanella d3573f61ac Fix wordsize-32 mmap offset for negative value (BZ#18877) 
This patch fixes the default wordsize-32 mmap implementation offset
calculation for negative values.  Current code uses signed shift
operation to calculate the multiple size to use with syscall and
it is implementation defined.  Change it to use a division base
on mmap page size (default being as before, 4096).

Tested on armv7hf.

	[BZ #18877]
	* posix/Makefile (tests): Add tst-mmap-offset.
	* posix/tst-mmap.c: New file.
	* sysdeps/unix/sysv/linux/generic/wordsize-32/mmap.c (__mmap): Fix
	offset calculation for negative values.
