I really don't see anything in that function that looks like a huge time

True, but the noise sums up, and the result is terrible speed of compiling
empty source files, something that e.g. Linux kernel or other packages
that have lots of small source files, care about a lot.
If initializing it early would buy us anything on code clarity etc., it
could be justified, but IMHO it doesn't, the code in libcpp already has the
delayed initialization anyway.
Well, it does buy us early (and reliable) error checks against the
environment variable.
