Cross toolchain packages
Hi -
Fedora MIPS doesn't seem to have cross toolchain packages like the
Fedora Arm support has (thanks to Lennert Buytenhek's work). It's a bit
old though since it was done as a one-off a couple of years ago on gcc
4.1 basis.
That's a shame because although Fedora mainly has a native build
approach, in fact for bootloaders and kernel a cross toolchain is very
useful.
I spent some time uplevelling the cross packages in Fedora ARM over the
weekend and was able to get them working for ARM kernel-building duties
with rawhide 4.5 gcc version.
Now I would like to see how difficult it would be to retarget those
packages to be compatible with Fedora MIPS stuff.
Attempting to recook binutils-2.20.51.0.7-5.fc14.src.rpm for
mipsel-softfloat-linu-gnueabi, which works OK with armv5tel, creates an
ld that fails its self-tests on MIPS ELF stuff.

make[5]: *** [check-DEJAGNU] Error 1
What is the toolchain basis for the MIPS packages that have been created
so far, and the triplet used?
