Set .file section explicitly for .S files to avoid
the linker introduces the host path in symbols for
object files whose source file is .S
Otherwise, there is a host path in the symbols as
below:
$ readelf --wide --symbols /my-build/boost/1.67.0-r0/boost_1_67_0/x86_64-poky-linux/boost/bin.v2/libs/context/build/aca09349fdb84d131321425f6c3a38ed/libboost_context.so.1.67.0
