Subject: [PATCH] crt: Add .file directive

Musl linked binaries come out to be not reproducible because
absolute build path is seen in debug info of crti.o and crtn.o
This is due to the fact that these objects are built from assembly
source files and they are missing .file directive
if we add .file <filename>.s in them then debug info encodes this
value instead of absolute path in debug_line section

Upstream-Status: Pending
