[meta-freescale] [PATCH] libsdl2: avoid basehash changes

[André Draszik]

When adding meta-freescale, the sstate basehash of libsdl2 changes
because EXTRA_OECONF_IMX is appended to EXTRA_OECONF unconditionally,
causing EXTRA_OECONF to now depend on EXTRA_OECONF_IMX, invalidating
the sstate.

This is particularly annoying for the native flavour of this
recipe, because qemu-native depends on libsdl2-native, causing a
massive rebuild of a lot of packages for no good reason, preventing
efficient sstate re-use across different machines.

Just drop EXTRA_OECONF_IMX and append to EXTRA_OECONF using
variable overrides directly.
