binaries run by qemu: link with -static, force ld.bfd

For machines using DEFAULTTUNE = "armv7ahf" or DEFAULTTUNE = "armv7athf" a build
of openjdk-7 fails with segmentation faults during the qemu-arm runs.

e.g.
Segmentation fault (core dumped) | qemu-arm -cpu cortex-a8 -s 2097152
  -L .../sysroots/colibri-t20 \
  -E LD_LIBRARY_PATH=.../sysroots/colibri-t20/lib ./mkbc - bytecodes_arm.s

I found that qemu-arm can not execute any binary which is compiled with the
resulting compiler and is linked with the gold linker and the -static flag.
Even a simple hello world program does not work. When executing that
hello world on the real hardware it also generates a segmentation fault.

Removing the -static flag or forcing the bfd linker fixed this.

Note that other machines, colibri-t30 or i.mx6 based ones with neon but
otherwise identical setup do not suffer from the issue.
DEFAULTTUNE = "armv7athf-neon" works.

While at it convert the sizer call for openjdk-7 used when building xawt
also to use -static even though the code is currently disabled.
