This breaks building on my RHEL 5 machine:

/home/uweigand/dailybuild/spu-tc-2015-01-15/binutils-gdb-head/binutils-gdb/gdb/nat/linux-personality.c: In function 'maybe_disable_address_space_randomization':
/home/uweigand/dailybuild/spu-tc-2015-01-15/binutils-gdb-head/binutils-gdb/gdb/nat/linux-personality.c:80: error: 'ADDR_NO_RANDOMIZE' undeclared (first use in this function)
/home/uweigand/dailybuild/spu-tc-2015-01-15/binutils-gdb-head/binutils-gdb/gdb/nat/linux-personality.c:80: error: (Each undeclared identifier is reported only once
/home/uweigand/dailybuild/spu-tc-2015-01-15/binutils-gdb-head/binutils-gdb/gdb/nat/linux-personality.c:80: error: for each function it appears in.)

It looks like this is because you replaced:
> -# if !HAVE_DECL_ADDR_NO_RANDOMIZE
by:
> +# ifndef HAVE_DECL_ADDR_NO_RANDOMIZE

but config.h on my machine without ADDR_NO_RANDOMIZE contains:
#define HAVE_DECL_ADDR_NO_RANDOMIZE 0
