chore(release): 0.4.8

Also used existing `CFLAGS` and `LDFLAGS` environment variable values,
so a user can easily set these when running the build script to add more
paths. Previously they were set to explicit values ignoring any existing
value.

This might help resolve issues where libgccjit.h is not found as
reported in issue #20. Though I have not been able to reproduce this
myself, it seems adding the libgccjit's include dir has solved the issue
for some.
