Allow reordered MAKEFLAGS

-R and -r (-Rr) can be reordered to -r and -R (-rR).
This happens with MSYS1/2 gnu-make and mingw32-make,
and triggers "Recursion detected, bailing out..."

     2  The generated libtool for building libstdc++ adds the -nostdlib option to the

     3  g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"

     4  error when linking against the libstdc++ shared object.  This patch adds gcc

     5  to the list of libraries linked against when linking libstdc++.
