Partial success on removal of all crazy libraries and includes from CFLAGS and LDFLAGS used throught EMBOSS sources. While compile commandline are now clean still libtool is passed with LDFLAGS carrying over the many X11 and graphics libraries. Seems the source is ltmain.sh which uses  on the linker lines but editing m4/libtool.m4 is not the right way to do it. Same applies to ltmain.sh in top-level directory. Any volunteers? Bug #394425
