If your cross-compiler is called differently than the default on in

Part of the problem is that there is no compelling default. The name of
the cross-compiler can vary depending on the chosen executable prefix or
the chosen target tuple.
Let's say I create new cross toolchains for both m68k and powerpc. I use
the "m68k-linux-gnu" to follow the m68k default, but let's assume powerpc
users prefer their default "powerpc-linux" so I follow that too. The
result is that I now have gcc's -B option working (or not working) in
suprising ways too.
Uniformity is more helpful downstream than a different arbitrary default
for each architecture. Debian should patch their default into their kernel
source packages if they've standardised on cross compiler prefixes.
what's the problem with calling?
make ARCH=myarch CROSS_COMPILE=my-cross-compile-prefx-
This has been working for +10 years on all non-ia32 platforms I ever worked on.
But there is no problem with calling that (?). Rob's patch doesn't change
this.
But it makes life harder for the people who use it daily.
If the consensus is to not provide default cross compiler prefixes in
arch/*/Makefile, fine for me, but IFF it's done for all architectures
(i.e. check with the blackfin, h8300, mips, parisc, and xtensa people
first).
