MIPS: remove a space after -I to cope with header search paths for VDSO
Commit9cc342f6c4
("treewide: prefix header search paths with $(srctree)/") caused a build error for MIPS VDSO. CC arch/mips/vdso/gettimeofday.o In file included from ../arch/mips/vdso/vdso.h:26, from ../arch/mips/vdso/gettimeofday.c:11: ../arch/mips/include/asm/page.h:12:10: fatal error: spaces.h: No such file or directory #include <spaces.h> ^~~~~~~~~~ The cause of the error is a missing space after the compiler flag -I . Kbuild used to have a global restriction "no space after -I", but commit48f6e3cf5b
("kbuild: do not drop -I without parameter") got rid of it. Having a space after -I is no longer a big deal as far as Kbuild is concerned. It is still a big deal for MIPS because arch/mips/vdso/Makefile filters the header search paths, like this: ccflags-vdso := \ $(filter -I%,$(KBUILD_CFLAGS)) \ ..., which relies on the assumption that there is no space after -I .
