commit: https://git.buildroot.net/buildroot/commit/?id=985543fcfe8327c5b6a137f6043c1bf76f10b456
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Build fails when linking with liblzma compiled without threads support.
./.libs/libarchive.so: undefined reference to `lzma_cputhreads'
./.libs/libarchive.so: undefined reference to `lzma_stream_encoder_mt'
So let's enable LZMA only when toolchain has threads support.
Fixes:
