Subject: implement arm eabi mem* functions
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=d8be1bc0193f45d3900f8466f26d1411b7f919c3;p=musl

implement arm eabi mem* functions

these functions are part of the ARM EABI, meaning compilers may
generate references to them. known versions of gcc do not use them,
but llvm does. they are not provided by libgcc, and the de facto
standard seems to be that libc provides them.
