dev-util/ccache: add USE=static-c++ which embeds libstdc++
To ease building gcc with ccache we need to handle the case of LD_PRELOAD=./inplace/libstdc++.so injected by gcc's build system. USE=static-c++ uses -static-libstdc++ for it. Reported-by: Mihai Moldovan Bug: https://bugs.gentoo.org/761220 Package-Manager: Portage-3.0.19, Repoman-3.0.3 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

ccache acts as a caching pre-processor to C/C++ compilers, improving
compilation time when recompiling previously compiled source.
