mesa: Avoid platform probing when building without EGL

The 17.1.2 release has changed the platform setting and when not
explicitly disabled it assumes x11 support.

Fixes:

| checking for x11-xcb xcb xcb-dri2 >= 1.8 xcb-xfixes... no
| configure: error: Package requirements (x11-xcb xcb xcb-dri2 >= 1.8 xcb-xfixes) were not met:
|
| No package 'x11-xcb' found
| No package 'xcb' found
| No package 'xcb-dri2' found
| No package 'xcb-xfixes' found
|
| Consider adjusting the PKG_CONFIG_PATH environment variable if you
| installed software in a non-standard prefix.
|
| Alternatively, you may set the environment variables XCB_DRI2_CFLAGS
| and XCB_DRI2_LIBS to avoid the need to call pkg-config.
| See the pkg-config man page for more details.

The issue has been exposed by meta-freescale BSP. Fix tested with
imx6qsabresd machine.
