egl/opengl: remove duplicate LDFLAGS
Fix autoreconf warning due to duplicate LDFLAGS
:
src/egl/opengl/Makefile.am:82: warning: eglgears_x11_LDFLAGS multiply defined in condition TRUE ...
src/egl/opengl/Makefile.am:71: ... 'eglgears_x11_LDFLAGS' previously defined here
src/egl/opengl/Makefile.am:83: warning: egltri_x11_LDFLAGS multiply defined in condition TRUE ...
src/egl/opengl/Makefile.am:72: ... 'egltri_x11_LDFLAGS' previously defined here
Both LDFLAGS
variables are defined to $(AM_LDFLAGS) $(X11_LIBS)
in both definitions, so either should be safe to remove.
