Slightly off-topic, but I am actually trying to manually build a musl
MIPS-III o32 seed stage (big-endian) using OpenADK as a base.  Haven't
gotten to gcc yet (the OpenADK base has 8.3.0), but any documentation or
other useful bits of info stored someplace that I oughta know about?

As Zorry noted in #Gentoo-hardened, we do not support anything less then
GCC-8 for musl right now so no need to add the stable ssp/pie blocks.
