Without the change profiled bootstrap fails for various warnings on
master branch as:
$ ../gcc/configure
$ make profiledbootstrap
...
gcc/genmodes.cc: In function ‘int main(int, char**)’:
gcc/genmodes.cc:2152:1: error: ‘gcc/build/genmodes.gcda’ profile count data file not found [-Werror=missing-profile]
...
gcc/gengtype-parse.cc: In function ‘void parse_error(const char*, ...)’:
gcc/gengtype-parse.cc:142:21: error: ‘%s’ directive argument is null [-Werror=format-overflow=]
The change removes -Werror just like autofeedback does today.
