>Fix:
i thought, thie error might come from arm-neon-assembler.
therefore, i tried to recompile with "--disable-arm-neon", and compile succeeded.

in the process, i also find a typo in Makefile.

so i make a patch file to fix these problems, and attach it.

this patch will apply "--disable-arm-neon" for "arm" or "armv6" boards.
i think this issue does not affect only RPI, also other arm boards.
because of pixman-arm-neon-asm.S might be not written for FreeBSD.
