boost: Improve reproducibility

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:

Subject: [PATCH] make_x86_64_sysv_elf_gas.S: set .file section
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
