This is a problem with GCC 8, not ccache. You should have

/usr/pkg/gcc8/libexec/gcc/x86_64--netbsd/8.4.0/liblto_plugin.la
/usr/pkg/gcc8/libexec/gcc/x86_64--netbsd/8.4.0/liblto_plugin.so
/usr/pkg/gcc8/libexec/gcc/x86_64--netbsd/8.4.0/liblto_plugin.so.0
/usr/pkg/gcc8/libexec/gcc/x86_64--netbsd/8.4.0/liblto_plugin.so.0.0

installed and these should end up in .buildlink directory.

Can you check?

Kind regards,
Adam
