gcc-config: Check writability in env.d instead of EROOT
SELinux blocks access to / so gcc-config fails even tho the required
dirs are writable. Adding SELinux rules to allow writing to / is pretty
undesirable. The best is to check for writability in the actual dirs
that gcc-config needs to write.
It should be sufficient to check only one dir instead of every dir,
since the check for only EROOT has been sufficient in the past.
