this patch badly broke all -fprofile-generate/-fprofile-use tests in the
default case like this:
UNRESOLVED: g++.dg/bprob/g++-bprob-1.C compilation, -O0 -fbranch-probabilities
FAIL: g++.dg/bprob/g++-bprob-1.C compilation, -O0 -fprofile-arcs
ld: fatal: library -lgcov: not found
collect2: error: ld returned 1 exit status
compiler exited with status 1
FAIL: g++.dg/bprob/g++-bprob-1.C compilation, -g -fprofile-arcs
libgcov.a is not copied over from libgcc to gcc due to a typo in
libgcc/Makefile.in. Fixed as follows; will install as obvious once
bootstrap has finished.
