[Ipopt] building shared libraries under mingw doesnt work for me

We (=a number of COIN projects) are using libtool to generate the 
libraries.  Being afraid of breaking things we haven't updated the version 
of libtool we are using in a number of years, and we could not get that 
old version to properly produce shared libraries on msys, so we disabled 
this in the configure scripts.

This is not really an issue with the Ipopt project, but instead of the 
BuildTools COIN-OR project that provides configure and build tools for a 
number of COIN projects.  So, if you would like to continue a discussion 
about this, it probably makes more sense to do that on the BuildTools 
mailing list.

Regards,

Andreas
