>Description:
For the upcoming slave port libdrm-nouveau I need to set COMMENT for it. Because libdrm uses `=' instead of `?=' including ${MASTERDIR}/Makefile at the end of the slave port's Makefile inherits libdrm's COMMENT value and discards the one in libdrm-nouveau.
>How-To-Repeat:

>Fix:
Replace `=' with `?=' for COMMENT in graphics/libdrm/Makefile
