Ubuntu18.04报错：make[1]: *** No rule to make target armv4-mont.o, needed by build-msm8916/lk. Stop.

报错：make[1]: *** No rule to make target build-msm8916/lib/openssl/crypto/bn/asm/armv4-mont.o, needed by build-msm8916/lk. Stop. 

解决：bootable/bootloader/lk/lib/openssl/crypto/bn/asm/armv4-mont.s
将armv4-mont.s改为armv4-mon.S
