[PATCH] boost: Improve reproducibility

[<mingli.yu@windriver.com>]

From: Mingli Yu <mingli.yu@windriver.com>

boost_context includes some assembly source
files and will export the assembly object file
make_x86_64_sysv_elf_gas.o which contains host
path 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
42: 0000000000000000 0 FILE LOCAL DEFAULT ABS /my-build/boost/1.67.0-r0/boost_1_67_0/x86_64-poky-linux/boost/bin.v2/libs/context/build/aca09349fdb84d131321425f6c3a38ed/asm/make_x86_64_sysv_elf_gas.o

Enable stirp for boost_context to hidden the
symbols
