Fix toybox build with C99 compilers toybox "make menuconfig" currently fails to build if the compiler is in C99 mode (clang 3.6 and gcc 5.0 snapshots default to C99 mode, you can also reproduce the failure with older gcc by using 'make menuconfig HOSTCC="gcc -std=gnu99"'). The problem is that inline semantics changed in C99, and kconf_id_lookup's inline-ness depends on C89 semantics there.
