Looks like configure detected that your system had localcharset.h which 
should have prototyped a function called locale_charset() which we use 
to get the user's locale charset.

You might be able to fix this by commenting out the #define 
HAVE_LOCALCHARSET_H in config.h

Alternatively, it looks like it might be a part of libiconv (solution 
below).

These errors suggest that configure detected that you had libiconv 
installed, so it tried to use it but apparently thought it was part of 
your libc because I do not see a -liconv in the link line.

I fixed an issue similar to this yesterday, maybe your version of mono 
from git is older than my fix (commit = 
1deef5a760b37cf1e42a60110981d0f752d84d9d ). You can either try updating 
from git or add $(LIBICONV) right after each ($GLIB_LIBS) in the 
Makefile.am files and then rebuild.

Hope that helps,
