MIPS: vdso: Define BUILD_VDSO32 when building a 32bit kernel
The confinement of the 32bit specific VDSO functions missed to define
BUILD_VDSO32 when building a 32bit MIPS kernel:
arch/mips/vdso/vgettimeofday.c: In function __vdso_clock_gettime:
arch/mips/vdso/vgettimeofday.c:17:9: error: implicit declaration of function __cvdso_clock_gettime32
arch/mips/vdso/vgettimeofday.c: In function __vdso_clock_getres:
arch/mips/vdso/vgettimeofday.c:39:9: error: implicit declaration of function __cvdso_clock_getres_time32
Force the define for 32bit builds in the VDSO Makefile.
Fixes: bf279849ad59 ("lib/vdso: Build 32 bit specific functions in the right context")
