Subject: [PATCH] Adopt language-specific %build_fooflags macros from Fedora

%{optflags} has been the catchall for all compiler options but this
is quite limiting as there's no way to add for example C++ specific
options distro-wide. This adds separate %build_cflags, %build_cxxflags,
%build_fflags for the gcc-supported languages, and additionally
%build_ldflags for distro-wide LDFLAGS setting.

Based on Florian Weimer's work in Fedoras redhat-rpm-config macros.
