I see this difference in the build.log

f31 [1]:
Checking for pkg-config opengl ... no
Checking for opengl ... yes
adding -lGL to LIBS_X11
adding -lGLU to LIBS_X11

f32[2]:
Checking for pkg-config opengl ... adding -lOpenGL to LIBS_X11
yes


the part in the code is:

check_deps

# need -lm for ceil/floor in HUD OSD
enabled xrender && add_flags "LIBS_X11" "-lm"
# need -ldl and -lpthread with opengl
enabled opengl && add_flags "LIBS_X11" $LIBS_DLFCN $LIBS_PTHREAD
# need -ldl for dlopen() in vdr plugin
enabled vdr && add_flags "LIBS_VDR" $LIBS_DLFCN

what is the easiest way to set the "LIBS_X11" for f32 and where should it be set?
