Import ashldr3, ashrdi3 and lshrdi3 to squash possible libgcc fp mismatch, resulting in the following warning:
mips-linux-gnu-ld: Warning: /usr/lib/gcc/mips-linux-gnu/4.7/libgcc.a(_lshrdi3.o) uses hard float, u-boot uses soft float mips-linux-gnu-ld: Warning: /usr/lib/gcc/mips-linux-gnu/4.7/libgcc.a(_ashldi3.o) uses hard float, u-boot uses soft float

[MIPS] Fix optimization for size build. It took a while longer than on other architectures but gcc has finally started to strike us as well ... This also fixes the damage by 6edfba1b33c701108717f4e036320fc39abe1912.

I removed that last line as demanded by Wolfgang.
applied to u-boot-mips/master, thanks
