Removed confusing comment in configure.sh, and extra variable

In the previous commit, we remove the `-static' flag from building PatchELF
because it wasn't necessary any more. Howver, the comment for the check
still included it and could be confusing. This is corrected with this
commit. Also, we don't need the `good_static_libc' variable (that was only
defined to pass onto PatchELF). This has also been corrected.

 # See if a link-able static C library exists
 # ------------------------------------------
 #
-# After building GCC, we must use PatchELF to correct its RPATHs. However,
-# PatchELF links internally with `libstdc++'. So a dynamicly linked
-# PatchELF cannot be used to correct the links to `libstdc++' in general
-# (on some systems this causes no problem, but on others it doesn't!).
-#
-# However, to build a Static PatchELF, we need to be able to link with the
-# static C library, which is not always available on some GNU/Linux
-# systems. Therefore we need to check this here. If we can't build a static
-# PatchELF, we won't build any GCC either.
+# A static C library and the `sys/cdefs.h' header are necessary for
+# building GCC.
