Since automake deprecated the INCLUDES name in favor of AM_CPPFLAGS,
change all existing users over. The generated code is the same since
the two variables have been used in the same exact places by design.
There are other cleanups to be done, but lets focus on just renaming
here so we can upgrade to a newer automake version w/out triggering
new warnings.
The code accessing the floating point control/status register, namely
#define __cfc1(__fcsr) __asm __volatile("cfc1 %0, $31" : "=r" (__fcsr)
does not compile with mips16. This changed the makefile to pass -mno-mips16 to avoid the following
compiler error:
mips-mti-elf fails with "Error: unrecognized opcode `cfc1 $3,$31'"
