Looks like I messed up the fix pretty nicely actually....

Because the final archive is created from an ar archive, to which each .o file
is added using the 'r' replace flag.  And because the arch specific stuff comes
after the common stuff, then by using the same file name this allows the v850
_mmap.o file to replace libc/sysdeps/linux/common/_mmap.o so that the arch
specific mmap definition ends up being the one in the final binary.
