introduce CPPFLAGSAUX

Otherwise CPPFLAGS will be used as-is, which are the CPPFLAGS for the host we're building for:

configure:3157: checking whether the C compiler works
configure:3179: x86_64-pc-linux-gnu-cc -march=native -O2 -pipe -march=armv7-a -mfloat-abi=hard -mfpu=vfpv4 -pipe -O2  conftest.c  >&5
x86_64-pc-linux-gnu-gcc: error: unrecognized command line option '-mfloat-abi=hard'
x86_64-pc-linux-gnu-gcc: error: unrecognized command line option '-mfpu=vfpv4'
configure:3183: $? = 1
