Make sure to read the documentation at 
"http://www.graphicsmagick.org/INSTALL-unix.html" and also 
http://www.graphicsmagick.org/README.html

The "--without-x option" has always worked for me.

Check the configure summary at the end of the configure run.

Using

configure '--disable-shared' '--enable-static' '--enable-silent-rules' 
'--disable-openmp' '--without-threads' '--without-modules' 
'--without-bzlib' '--without-dps' '--without-jbig' '--without-jpeg' 
'--without-jp2' '--without-lcms' '--without-lcms2' '--without-lzma' 
'--without-tiff' '--without-trio' '--without-ttf' '--without-webp' 
'--without-wmf' '--without-zlib' '--without-x' '--without-png' 
'--without-zstd'

disables all possible add-on features.

User-provided CFLAGS, CXXFLAGS, CPPFLAGS, LIBS, and LDFLAGS are 
honored in a useful fashion.

I don't know anything about AC_APPLE_UNIVERSAL_BUILD but assume it is 
intrinsic to Autoconf since I see mention of it but I did not 
explicitly add support for it.

Things change very slowly in GraphicsMagick so defines used now are 
mostly what they were 10 years ago.
