[PATCH] MIPS/Linux: Enable creation of the RELRO header

[Maciej W. Rozycki]

Hello,

 Do we have any particular reason to set DATA_ADDR to 0x10000000 for 
traditional o32 targets as used by Linux?  I don't think so -- it just 
happens to come from Irix defaults and we probably don't need such a close 
compatibility.  OTOH, getting rid of that DATA_ADDR would let us make use 
of the "-z relro" option, like other Linux ports (including new MIPS ABIs) 
do.

 Here's my proposal.  It doesn't cause any regressions for a native run on 
mipsel-linux-gnu.  It works for me as expected with glibc 2.3.5.

	* emulparams/elf32btsmip.sh: Unset DATA_ADDR.

 OK to apply to the HEAD?
