[OE-core] [PATCH 0/2] Handle the hossttools directory when restoring from the sstate cache

[Peter Kjellerstedt]

After the introduction of copying host tools to the build directory
and cleaning out $PATH, we got a problem with one of our tools. It
turned out that its configure.ac uses AC_PATH_PROG(PERL, perl) to
locate the perl interpreter, and uses that on the shebang line of the
installed tool. Previously it found /usr/bin/perl and used that, but
now it will find ${TMPDIR}/hosttools/perl and use that instead, which
means that if the tool is restored from the sstate cache in another
build directory than where it originated from, the path will be wrong.

These two patches adds a new variable (HOSTTOOLS_DIR) for the
${TMPDIR}/hosttools directory, and then makes sure it is handled by
the staging code so that any references to its value are properly
corrected when restoring from the sstate cache.
