This is needed for host packages built in very early stages,
before host-cc (which typically uses ccache) is available.
Set CC/CXX to LOCAL_CC/CXX in this case.

Default linker can be set with DEFAULT_LINKER in options.
Packages can influence linker selection both by positive and/or
negative PKG_BUILD_FLAGS, eg +bfd or -gold.
Positive build flags take priority over the default linker so eg
DEFAULT_LINKER="gold" and PKG_BUILD_FLAGS="+bfd" will select bfd.
Negative flags mean a specific linker should not be used, eg -gold
prevents using gold.
If the default linker is disabled via a build flag then any other
available linker will be used.
Optional linkers like gold have to be enabled with eg GOLD_SUPPORT="yes"
in options. If an optional linker is not enabled it won't be a candidate
for linker selection. So eg "+mold" will have no effect if MOLD_SUPPORT
isn't set to "yes".

Some addon dependencies do this locally on their own. With this, these
packages can now use the standard makeinstall() functions and access build
artifacts using get_install_dir() without polluting the sysroot folder.
