Am I perhaps asking in the wrong place? I could really use some help here. I
now have a complete Rust cross-compiler working and have set the various env
vars and created a mozconfig file. But I'm getting this:
$ ../configure --target=sparcv9-sun-solaris
...

It appears it's using the wrong target gcc and the wrong rustc too.
Part of the problem may be this (confusing) statement in the cross-compiling
guide:
"The main thing to remember is that when --target=${xtarget_arch} is passed to
configure, configure expects to find the compiler toolchain as
${xtarget_arch}-TOOL where TOOL is gcc, g++, ranlib, etc."
So if my target is "sparcv9-sun-solaris", then it's going to look for
"sparcv9-sun-solaris-gcc"? Where? That's not a complete file specification.
FWIW, mine is here:
/usr/sparcv9-solaris/solaris/cross/sparcv9-solaris2.11/bin/sparcv9-solaris2.11-gcc
Any help would be most appreciated.
