git: rtld: Shrink by eliminating stdio
commit b2cf26499615896e389f50012c0bf803e99bc7f3

rtld: Shrink by eliminating stdio
Eliminate stdio for parsing libmap.conf, and instead parse it from direct
mapping. Also stop using strerror(3) in rtld which sucks in msgcat and
stdio. Instead directly access sys_errlist array of error messages with
private rtld_strerror() function.
Results on x86_64 (includes debug symbols):
