[Buildroot] [PATCH] sawman: Link using gcc instead of ld

Using ld may cause a link failure due to using the default emulation
linker which is configured when building the linker in binutils.  Using
gcc instead will pass the appropriate -m value because the compiler
knows the ABI you are using.

Here is an example of the failure:

ld: .libs/libdirectfbwm_sawman.a.tmp/sawman_wm.o: ABI is incompatible
with that of the selected emulation
ld: failed to merge target specific data of file
.libs/libdirectfbwm_sawman.a.tmp/sawman_wm.o
ld: Attempt to do relocatable link with elf64-tradbigmips input and
elf32-tradbigmips output
ld: .libs/libdirectfbwm_sawman.a.tmp/sawman_wm.o: file class ELFCLASS64
incompatible with ELFCLASS32
ld: final link failed: File in wrong format

Fixes:
