Can you provide the two logs separately, the one for Firefox
/home/ashish/oe-core/build/tmp-glibc/work/armv7ahf-neon-mx6qdl-angstrom-linux-gnueabi/firefox/38.8.0esr-r0/temp/log.do_compile.22207
and the one for libarchive
/home/ashish/oe-core/build/tmp-glibc/work/x86_64-linux/libarchive-native/3.2.2-r0/temp/log.do_compile.10932
The combined log has too much data to parse easily.
