First switch the architecture availability to positive logic since it's
cleaner and avoids issues when new ones are introduced.
Then look at the source for the available ones at sysdeps/linux-gnu/...
aarch64 -> NULL
arc -> NULL
arm -> hardcoded to little endian, so no armeb
avr32 -> NULL
blackfin -> NULL
microblaze -> NULL
mips -> little/big endian handled but not for 64 bits
nios2 -> NULL
ppc -> OK
sh -> NULL
sparc -> OK
x86 -> Both i386 and x86_64 handled
xtensa -> NULL
