Hello, attached patch adds Fortran compiler to Gentoo override rules in cmake-utils.eclass the same way C/C++ compilers are added.
This change is needed because packages which force their own precedence of Fortran compilers or flags also exists. We hit this issue on bug 486626 [1] for sci-libs/lapacke-reference (science overlay): if multiple Fortran compilers are installed, e.g. pathf95 and gfortran, package prefers pathf95 — this may even broke build, because most FCFLAGS are not compatible between this compilers In order to fix this FC should be set from $(tc-getFC), which is implemented in proposed patch as well as ensuring proper flags are set. This change was already discussed with KDE team [1] and I'm going to commit this patch after feedback or in a week if there are no objections.
