[Libsigcx-main] Patches for various things

[Steven B. <sw...@uc...>]

I'm going to be using libsigcx on PDAs, so I needed to fix it up to 
handle cross-compiles and whatnot via OpenEmbedded.  I have a few 
patches here that'd be nice to have applied to the arch repository.

This fixes the dist target, where autogen.sh wasn't being disted, and 
libtool.m4 was.  Disting the libtool.m4 was causing issues, as if you 
tried to regenerate the build files with a newer libtool, libtool.m4 (no 
longer used) would still be there, and get included by aclocal, causing 
quite a mess:

This fixes pack<R,P1> being used before it was declared by predeclaring 
it.  On newer gccs, this would prevent the tests from compiling.  There 
might be other similar issues that will pop up over time due to the 
templated classes having their members declared inline.

This fixes AC_TRY_RUN getting called in the exception handling test even 
during cross compiles.  That macro can't be called during cross compiles 
or it will error (for obvious reasons).  Assume it passed in such a 
case, as is the accepted way of handling AC_TRY_RUN tests.

The others in that dir are either already applied (the build fix I sent 
to the list earlier), or are just regenerations of files.  If anyone on 
the list is interested in OpenEmbedded, though, the package metadata 
I've put together can be found here:

I haven't ported the real application I have using it, yet, but this 
builds working ipk packages via bitbake, as I've copied over the tests 
to the PDA and they seem to have run fine.
