[Ipopt] Problem compiling IpOpt with Mingw

[Stefan Vigerske]

Hi,

if it's only the linear solver loader that makes the linking fail, then
you may just add --disable-linear-solver-loader to your configure call.
This should not harm as long as you have some linear solver available at
Ipopt build time (e.g., Mumps, Pardiso, or MA27).
