DO NOT REPLY [Bug 47691] New: libtool invocations should use --tag

This thread is where the issue was originally detected:
http://thread.gmane.org/gmane.comp.gnu.libtool.general/10315
http://thread.gmane.org/gmane.comp.gnu.libtool.general/10308

One problem with the Apache build is that it does not use the --tag option
with libtool.  This prevents certain things that a user building httpd
might want to do.

First off, --tag is not needed if the C or C++ compiler used during the build
is identical (read: string comparison) to that used during configure time.
The libtool script then uses the appropriate set of values by matching the
compiler name.  This is less efficient than telling libtool which set of
values to use by passing --tag, but not a problem.

However, sometimes one wants to override the compiler at 'make' time, for
example to use purify as indicated above.  The error you then get from
  make CC='purify gcc'

is something like

  libtool: compile: unable to infer tagged configuration
  libtool: compile: specify a tag with `--tag'

and could have been prevented with the following patch.

fix the same problem for apxs

Please apply Ralf's patch, and also the one I'm attaching now which fixes the
same problem for apxs. The MacPorts project has fielded many bug reports over
the years caused by this problem; we're now applying these patches locally to
work around it.
