Vladimír Čunát 5dfe6fd034 perl: fix evaluation on cygwin
... and maybe on other platforms that have `stdenv.cc.cc == null`.
No hash changes where it did evaluate previously. Discussion:

# Instead of silently building an unthreaded perl if this is not the

# In the case of stdenv linux boot stage1 it's not possible to use
