Integrate gcc 3.4.2 and add patches from both openembedded (6??-*)

  and Dan Kegel's crosstools (7??-*).
Use makefile vars for toolchain names in ccache.mk and gdb.mk.
Fix a g++-related symlink issue with ccache.
Change the default to gcc 3.4.2 and binutils 2.15.91.0.2 (now that mips
is building).  Let the users go forth and test...  ;-)

+
+This means that the unknown character is no longer ignored, despite the
+comment.  As a side effect a line starting with a line comment character
+not followed by APP in NO_APP mode now triggers an error instead of just a
+warning, breaking builds of glibc on m68k-linux.  Earlier in
+read_a_source_file where #APP is handled there is another comment that
+claims that unknown comments are ignored, when in fact they aren't (only
+the initial line comment character is skipped).
+
+Note that the presence of #APP will mess up the line counters, but
+that appears to be difficult to fix.
+
+Andreas.
