[Buildroot] [PATCH] Fix GDB BFD test linking

[Buildroot] [PATCH] Fix GDB BFD test linking

[Paulius Zaleckas]

When compiling GDB for target (in my case i386) it links
wrong BFD library from host OS. This prevents GDB from compiling
support for ELF and thus GDB is unusable on target.

More about this issue was already posted at:
http://lists.uclibc.org/pipermail/buildroot/2009-March/026585.html

Fix this issue by forcing ELF support.

[Buildroot] [PATCH] Fix GDB BFD test linking

[Paulius Zaleckas]

When compiling GDB for the same architecture as host it links
wrong BFD library from host OS. This prevents GDB from compiling
support for ELF and thus GDB unusable on target.

Fix this by moving BFD and libiberty directories before CFLAGS, since
"wrong" path comes from CFLAGS.
