 > Commit f4a61d1ae23e (package/pkg-meson.mk avoid host ccache detection)
 > forced the host C and C++ compilers so that meson does not try to
 > autodetect ccache, and instead relies on what we provide.

 > However, this incorrectly used single-expansion of variables in a
 > package infra.

 > For traditional builds, this is OK, because the value does not change
 > across packages.

 > However, for builds with per-package directories, this value only refers
 > to the generic path, which ill not exist until the end of the build when
 > all packages are aggregated in the host-finalize step.

 > Fix that by postponing the variable evaluation like all the others.
