Emacs HEAD broken with XPM option in 1b492fa

[Ashish SHUKLA]

Hi,

I came across following build error in configure script, while building Emacs
git revision 1b492fa[1] on FreeBSD 11.1 amd64:

Following is the configure line:

It seems like in e88bbd22[2], author (cc'ed) typo-ed (s/X11/noX/):

After updating the last line, configure script run finishes as expected
without any issue.

Happy to file a bug report, if it's reproducible elsewhere too.

Could you please look at this ?
