commit: http://git.buildroot.net/buildroot/commit/?id=21a0c11a90f9ff19c78a5f32e0a2e9064fd28054
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When building gdb for the host, we properly pass the PATH (through
HOST_CONFIGURE_OPTS) during the configure step, but we forget to do so
for the compilation step.

The result of this is that when the Crosstool-NG backend is used, gawk
is built and installed in $(HOST_DIR), as a dependency of the
crosstool-ng package.

Then, the host gdb configure script detects this gawk binary
($(HOST_DIR) is in the PATH), and assumes gawk is
available. Unfortunately, during the compilation step, it fails to
find the expected gawk binary, because $(HOST_DIR) is no longer in the
PATH. This causes the following build failure:

  http://autobuild.buildroot.org/results/067d0c2ea01673ba98ec11de2426f1ab92dac800/build-end.log

In order to fix this, we simply call the compilation step of gdb for
the host with $(HOST_MAKE_ENV), as it should have been done from the
beginning.
