[Buildroot] [PATCH] valgrind: remove default flags -mips32 and -mips64 from Makefile.all.am

[Vicente Olivert Riera <Vincent.Riera@imgtec.com>]

During configuration of Valgrind we check does the compiler support
-march=mips32 and -march=mips64. If compiler supports these flags we are
using them as default flags for mips32 and mips64.

"VALGRIND_AUTORECONF = YES" needs to be added to valgrind.mk because
this patch modifies the configure.ac.

Original upstream patch:
   https://github.com/svn2github/valgrind/commit/fdf6c5aea4671c3c43c90230510735d215dd1e1c

Fixes:
