As said in the commit log, directfb fails to detect tslib at configure
stage. There is no autobuilder failure as it doesn't cause a build
failure, only a runtime problem when trying to use directfb with tslib:
it just doesn't work.

I don't know why directfb is checking for package name "tslib-1.0" but
in Buildroot's pkg-config, package is named "tslib". So at configure
time directfb doesn't find tslib in pkg-config list, and choose to not
compile tslib support.

Please find attached a sample defconfig showing the problem. My patch
was runtime tested on ARM9.

Best regards,
Julien
