getenv() is MT-safe, as long as other threads don't use setenv()
or putenv(). It setenv/putenv that are not MT-safe, except in very
recent glibc versions.
If getenv() were not MT-safe, all the multithreaded programs that
use gettext() would have had a problem, because gettext() uses
getenv ("LANGUAGE").

Alternatively, you could override the 'cpu-supports' module with a
simpler one, via
https://www.gnu.org/software/gnulib/manual/html_node/Extending-Gnulib.html ,
and then you can still use the crc-x86_64 optimization.
