configure vs libtool mismatch after PR 14072 change

[Roland McGrath <mcgrathr at google dot com>]

This probably has the same cause as what Tom noticed.

Today's change:

broke the build in the nonobvious way that the binutils/ and gas/
directories just don't produce any linked binaries.  There is no
error, but e.g. as-new is never created.  The install rules then
don't complain about it being missing, but just don't install it.

The culprit appears to be the configure regeneration, which has some sort
of mismatch between what configure wants and what ltmain.sh contains.  The
result is that the generated */libtool scripts wind up omitting all the
useful parts of the script, so they happily do nothing and exit with 0.

I intend to retain my carefully-preserved ignorance of the innards of the
abomination that is libtool.  So I have no idea how to fix this.  I imagine
that it just means the configure turd parts of the libtool hooey and the
lt* files need to be updated in tandem and were accidentally allowed to drift.


Thanks,
