No -fno-profile-generate is needed for the (4 or 5) programs like sfnt2fnt if
you build this way:

make distclean && CFLAGS="-Wall -g -O2 -fprofile-generate"
LDFLAGS="-fprofile-generate -lgcov" ./configure --host=x86_64-linux-gnu
--build=x86_64-linux-gnu && make


However this again leads to a gcov error, this time in libwinecrt0

make[2]: Entering directory
`/home/scott/src/wine-1.1.23-oldprofiled/dlls/avifile.dll16'
../../tools/winegcc/winegcc -m32 -B../../tools/winebuild --sysroot=../..
-shared ./avifile.dll16.spec         
-Wb,--subsystem,win16,--main-module,avifil32.dll -o avifile.dll16.so 
-lavifil32 -lkernel32  ../../libs/port/libwine_port.a  -fprofile-generate
-lgcov 
../../dlls/winecrt0/libwinecrt0.a(dll_entry.o): In function
`__wine_spec_dll_entry':
/home/scott/src/wine-1.1.23-oldprofiled/dlls/winecrt0/dll_entry.c:30: undefined
reference to `__gcov_indirect_call_profiler'

I will note that some dlls seem to build and link fine.
