[oe] gcc-cross-initial.inc DEPENDS on libc-initial, but why conditionally on TARGET_ARCH?

[Leon Woestenberg]

Hello,

OE toolchain question: any reason why the list below includes arm*,
mips* but nothing else?

gcc-cross-initial.inc:

DEPENDS = "virtual/${TARGET_PREFIX}binutils"
DEPENDS += "${@['virtual/${TARGET_PREFIX}libc-initial',''][bb.data.getVar('TARGET_ARCH',
d, 1) in ['arm', 'armeb', 'mips', 'mipsel']]}"
PROVIDES = "virtual/${TARGET_PREFIX}gcc-initial"
PACKAGES = ""

(I'm tracking down a parallel make issue, this seems to cause/trigger
it as I build for powerpc).

Thanks,
