rpm 4.0.3 (the default) on redhat 7.2 doesn't pass --target properly

[Michael Taht <mtaht mvista com>]

rpm  --define _topdir\ /home/mtaht/hhl201/mobile/freetype \
--define _builddir\ /tmp/ \
--define _srcrpmdir\ /home/mtaht/SRPMS --define _target\ arm_sa_le \
--define _hhl_target_arch\ arm_sa_le --define _rpmdir\ /home/mtaht/RPMS \
--define _hhl_build_id\ custom --define "vendor MontaVista Software, Inc." \
--define "packager <mtaht@mvista.com>" --target=arm_sa_le -ba 
SPECS/hhl-target-freetype.spec

returns:

--target=arm_sa_le: unknown option

Using --target arm_sa_le has "interesting" results. That way, it mangles 
what
gets passed to rpmbuild.

The workaround is to call rpmbuild directly, but that doesn't work for 
all cases.

For example, I'm calling rpm -q --specfile bla.spec to determine some build
info from the specfile. --target's stuff (for example _hhl_cross_dir, 
which is defined
in a custom macros file) needs to be defined properly to get coherent 
information back.
--define _target\ arm_sa_le doesn't seem to help.

Any suggestions?
