LSB

Current Best Effort Linker uses a set of fixed paths for the dynamic loader.

Should we concider expanding this to include envormental vars like LSB_LD_SO for path to lsb ld so file and LSB_PLATFORM_LD_SO for the distributions ld.so.

I know making lsb relocatable does not seam a requirement.   With items like android using the / may not be a option.   So the FHS offset to another directory maybe required.  Should Best Effort be made support this.
