added -I/Users/nsantos/android/ndk/platforms/android-9/arch-arm/usr/include
to CFLAG var inside Makefile. Tried to call make build_libs again. The
output was better as it actually started to compile, however, when it got
to the final phase this error occurred:

I have no experience with cross building, but just to make sure: Are you
exporting these variables? Otherwise configure/make will not pick them up.
