[Buildroot] [git commit] gcc: fix libstdc++_pic for AVR32

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=24c5dbcef21d61bc4482587eb8821159f69b245d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

It is not clear why 300-libstdc++-pic.patch pre-applied to
gcc-4.2.2-avr32-2.1.5 seems to have come from some older version
of gcc (as early as 4.0.3). This older patch incorrectly refers to
object files to be included in the library libstdc++_pic.a as *.o,
while their location seems to be in .libs/*.o (see the contents at
e.g. https://github.com/ZigFisher/Midge/blob/master/toolchain/gcc/4.0.3/300-libstdc%2B%2B-pic.patch ).
The same patch for gcc 4.1.0 refers to the files as .libs/*.o (see
https://github.com/ZigFisher/Midge/blob/master/toolchain/gcc/4.1.0/300-libstdc%2B%2B-pic.patch ).
This patch corrects rules in Makefile.in.

+libstdc++-v3: fix the effects of pre-applied 300-libstdc++-pic.patch
+
+This version of GCC comes with a number of pre-applied patches, among which is
+300-libstdc++-pic.patch that makes a PIC version of libstdc++. The resulting
+Makefile.in incorrectly refers to object files that should be insde the library.
