package/pkg-meson.mk: fix setting host C++ compiler

Browse Source 
Commit f4a61d1ae2 introduced CC_FOR_BUILD and
CXX_FOR_BUILD to avoid detecting ccache.

Both values are set to `HOSTCC`. This causes issues where C++ files are
compiled with the C compiler without passing the `stdc++` flag to the
linker, too.

Therefore, switch to pass the C++ compiler to CXX_FOR_BUILD.

Correctly fixes:

Commit 9783c04aaf proposed a fix which in
fact is a workaround to get Meson to pass the `stdc++` flag to the C
linker.

A follow-up commit will revert this commit, as it is no longer
needed.
