We already have a program that we link as soon as libgcc is created;
perhaps we could compile and assemble that program before starting to
build libgcc, and print some long error message explaining potential
problems and solutions if the program fails to compile?

Perhaps we could even split the compilation in assembly-generation and
assembling, such as to be able to tell whether the problem is the lack
of target libraries or of an assembler.
