The idea behind the cross-gcc package in Fedora is that it's for kernel builds
and bootloader-type things only. It builds libgcc, but doesn't use kernel
headers or a C library[*] as this enormously simplifies things.
The reasons being:
(1) Not all arches can use the same set of C libraries (some can't use glibc
and some don't have a uClibc port).
(2) I can only build each individual compiler against a single C library - so
if you have two or more incompatible environments, you're out of luck -
I can only use one.
(3) Building lots more compilers for individual environments would massively
increase the build size and time. A full cross-gcc build now takes the
best part of a day to build.
[*] Yes, there's one exception: it builds the arm compiler against an arm
cross-glibc - not my idea.
