[U-Boot-Users] [PATCH] 85xx: Add -mno-spe to e500/85xx builds

[Kumar Gala]

Newer gcc's might be configured to enable autovectorization by default.
If we happen to build with one of those compilers we will get SPE
instructions in random code.

-mno-spe disables the compiler for automatically generating SPE
instructions without our knowledge.
