It doesn't seem to like my --cross-prefix being a full path rather

When I forced --host=powerpc-linux into the pixman configure command
in QEMU's generated Makefile, it got past that, but it built
everything with the native compiler:
checking build system type... x86_64-unknown-linux-gnu
checking host system type... powerpc-unknown-linux-gnu
checking for powerpc-linux-gcc... no
checking for gcc... gcc
Looking a bit more closely, it seems that it's the QEMU rather than
pixman's autoconf that is making the bad assumption about the format
of --cross-prefix (I really wasn't up for wading in autoconf).
Running basename on cross-prefix and explicitly supplying CC and
such to pixman would help, though there still should be a way to
pass in an explicit host tuple if you have an unusually-named
toolchain.

Indeed, --cross-prefixdoes not support absolute path names.
I assume that the executables in
/home/scott/fsl/tc/gcc-4.5.55-eglibc-2.11.55/powerpc-linux-gnu/binare
without prefix
(gcc, ld, ...).
No, they are with prefix, just not in $PATH. I have more than one
"powerpc-linux-gnu" toolchain and I don't want to mess with my $PATH
constantly to choose between them.
Then there must also be the same executables with prefix
(powerpc-linux-gnu-gcc, powerpc-linux-gnu-ld, ...). These must be
somewhere in PATH.
No. This was never a requirement before -- why now?
Use --cross-prefix=powerpc-linux-gnu-(note the "-" at the end).
Then pixman would be configured with --host=powerpc-linux-gnu and
should find
the compiler. It won't find the compiler powerpc-linux-gcc when its
real name is
powerpc-linux-gnu-gcc.
No, it's real name is
/home/scott/fsl/tc/gcc-4.5.55-eglibc-2.11.55/powerpc-linux-gnu/bin/powerpc-linux-gnu-gcc
