Fixed profiling of elf kernels.  Made high resolution profiling compile
for elf kernels (it is broken for all kernels due to lack of egcs support).

Renaming of many assembler labels is avoided by declaring by declaring
the labels that need to be visible to gprof as having type "function"
and depending on the elf version of gprof being zealous about discarding
the others.  A few type declarations are still missing, mainly for SMP.
