[Bug bootstrap/45321] New: [4.6 regression] ARM bootstrap failure due to stdarg_p change

["mikpe at it dot uu dot se" <gcc-bugzilla at gcc dot gnu dot org>]

Attempting to bootstrap gcc-4.6-20100814 (r163252) on arm-linux-gnueabi fails
due to a warning in stage2 and the default use of -Werror there:

/home/mikpe/gcc-4.6-20100814/gcc/config/arm/arm.c: In function
'arm_get_pcs_model':
/home/mikpe/gcc-4.6-20100814/gcc/config/arm/arm.c:3720:7: error: passing
argument 1 of 'stdarg_p' discards 'const' qualifier from pointer target type
[-Werror]
/home/mikpe/gcc-4.6-20100814/gcc/tree.h:4829:13: note: expected 'tree' but
argument is of type 'const_tree'
cc1: all warnings being treated as errors

make[3]: *** [arm.o] Error 1
