Hmm, to add to the confusion, this creates an working pixman.

I noticed that RSEL6 builds with different CFLAGS than RSEL7, probably
that's the next thing to test.

RSEL6: CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector --param=ssp-buffer-size=4 -march=armv5te'

RSEL7: CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector-strong --param=ssp-buffer-size=4
-grecord-gcc-switches   -march=armv5te -mfloat-abi=soft'
