Vladimir Serbinenko 285540e448 mips: Make the assembly-code N32-compatible.
There are no $t4 or $t5 in N32 but there are $a4 and $a5.

Vladimir Serbinenko eecdbebc84 Remove mips_attributes.
mips_attributes was introduced to work around clang problems with
-msoft-float. Those problems are now fixed and moreover .gnu_attributes
itself is unportable and creates problem with clang.

Revert "mips: Fix soft-float handling."

This partially reverts commit 6a4ecd276e.

Vladimir Serbinenko 6a4ecd276e mips: Fix soft-float handling.
Add -msoft-float alongside clang arguments to specify ABI.
Specify ABI in asm files explicitly.
This trigers asm warning due to gcc failing to propagate -msoft-float
but it's tolerable.
