with clean tool and obj dirs, the tool gcc that I built does not look in
this directory, eg for <mmintrin.h> included by pixman-mmx.c on i386

a simple file containing only an include statement

% cat t.c
#include <mmintrin.h>

with a 5.99.41 userland,

% ktruss -i /usr/tools/bin/i486--netbsdelf-gcc -mmmx -c t.c | grep mmintrin
       "#include <mmintrin.h>\n"
 23537      1 cc1      
__stat50("/usr/tools/bin/../lib/gcc/i486--netbsdelf/4.1.3/include/mmintrin.h.gch",
 0xbfbfdfa0) Err#2 ENOENT
 23537      1 cc1      
open("/usr/tools/bin/../lib/gcc/i486--netbsdelf/4.1.3/include/mmintrin.h", 0x4, 
0x1b6) Err#2 ENOENT
 23537      1 cc1      __stat50("/usr/include/mmintrin.h.gch", 0xbfbfdfa0) 
Err#2 ENOENT
 23537      1 cc1      open("/usr/include/mmintrin.h", 0x4, 0x1b6) = 5

and it finds it naturally, but during a build.sh build with --sysroot,

% ktruss -i /usr/tools/bin/i486--netbsdelf-gcc -mmmx 
--sysroot=/var/work/NetBSD-current/obj/destdir.i386 -c t.c | grep mmintrin
t.c:1:22: error: mmintrin.h: No such file or directory
       "#include <mmintrin.h>\n"
 27551      1 cc1      
__stat50("/var/work/NetBSD-current/obj/destdir.i386/usr/include/mmintrin.h.gch",
 0xbfbfdf70) Err#2 ENOENT
 27551      1 cc1      
open("/var/work/NetBSD-current/obj/destdir.i386/usr/include/mmintrin.h", 0x4, 
0x1b6) Err#2 ENOENT
       "mmintrin.h: No such file or directory"

it fails, yet the file

  /var/work/NetBSD-current/obj/destdir.i386/usr/include/gcc-4.1/mmintrin.h

does exist..
