Subject: [PATCH] tools build: Respect HOSTCFLAGS in 'fixdep' compilation

When refactoring the Makefile rules for 'fixdep', I open-coded the
compilation rule (avoiding the "Build" recursive make, and therefore
tools/build/Build.include). In doing so, I omitted HOSTCFLAGS, which was
previously part of the host_c_flags definition.

Add that back in, so builds get a matching set of host CFLAGS and
LDFLAGS for this step.
