+Subject: [PATCH 5/5] fix do_compile failed on mips
+
+Link with var-OS_LDFLAGS to fix the issue.
+Such as on mips:
+...
+|mips-wrsmllib32-linux-g++ -meb -mabi=32 -mhard-float ... -o libmozjs-52.so
+|/usr/include/c++/8.1.0/bits/atomic_base.h:514: error: undefined
+reference to '__atomic_fetch_add_8'
+...
+
+In recipe, set OS_LDFLAGS="-Wl,-latomic" could fix the issue.
