Removed a few variables, as they were only used to communicate
between the meson package and pkg-meson.mk and are not needed
anymore.
Moved cross-compilation.conf.in out of meson package.
Creating the cross-compilation.conf files for packages is now
using the original template.
To avoid duplicate code, the common sed pattern is stored in
a make variable.
Use explicit Buildroot variables for compiler tools,
and some fixes. (TARGET_LDFLAGS and TARGET_CXXFLAGS
were mixed up with PKG_TARGET_CFLAGS)
