Configure stripping off first argument to subdirs

[Daniel Jacobowitz]

I just spent a little while figuring out why my sysroot patches were broken,
and found that the problem is that configure is stripping out the first
option from ${ac_configure_args}.  This seems to be the problem:


baseargs=`echo " ${ac_configure_args} " | \
        sed -e 's/ --no[^ ]* / /' \
            -e 's/ --cache[a-z-]*=[^ ]* / /' \
            -e 's/ --sr[a-z-]*=[^ ]* / /' \
            -e 's/ --ho[a-z-]*=[^ ]* / /' \
            -e 's/ --bu[a-z-]*=[^ ]* / /' \
            -e 's/ --ta[a-z-]*=[^ ]* / /' \
            -e 's/ [^-][^ ]* / /' \
            -e 's/^ *//;s/ *$//'`

ac_configure_args=" --prefix=blah --with-sysroot=blah" at this point.  Note
the leading space.  -e 's/ [^-][^ ]* / /' then deletes " --prefix=blah".
Is the leading space the problem, or should that say "[^ -]" instead?
