When shared libraries are enabled, gdb will try to link a shared
libbfd.so against non-PIC libiberty.a found in $(HOST_DIR).
This non-PIC libiberty.a come from the Buildroot's internal toolchain.

But gdb build it's own version with PIC enabled which is linked to
libbfd.so.

Help gdb to find the right libiberty.a by setting the path in LDFLAGS.

Fixes:
