configure step fails for fltk-1.3.4-1

[LukaHorvat]

Following the guide here this step

./configure --enable-gl --enable-shared --enable-localjpeg --enable-localzlib --enable-localpng

fails with the following error

configure: loading site script /etc/config.site                                     
checking build system type... configure: error: /bin/sh ./config.sub -pc-msys failed
configure: WARNING: cache variable ac_cv_build contains a newline                   

I'm running Windows 10 and using a standalone MSYS2 installation (stack is instructed to use my installation, but it shouldn't matter because this part doesn't have anything to do with stack).

I can provide any additional details.

I recently got this to build on Win 10, with

stack build -fbundled 
# or whatever the syntax is for enabling flags

i.e. not via msys. Does that work for you?
