Yes, it is possible, if you set the package up suitably; usually you 
will segregate the files to be compiled with the build compiler into a 
separate directory from those to be compiled with the host compiler.  
For an example, you could take a look at how I did for the `man' 
package for MinGW: http://mingw.cvs.sourceforge.net/mingw/man/

(In this package, sources in the `tools' directory are compiled for the 
build platform, while the remainder of the package is compiled for the 
host).

FTR, your example is not self-consistent: if your cross compiler is 
called `mingw32-gcc', then you must specify `--host=mingw32' when you 
run configure.
