Sorry to get to the party late but I just grabbed:
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.8.0/x86_64-gcc-4.8.0-nolibc_powerpc64-linux.tar.xz
and built adma.o without issue.
I used 44x/katmai_defconfig with the following additions.
+CONFIG_DMADEVICES=y
+CONFIG_AMCC_PPC440SPE_ADMA=y
Yours Tony.
