The attached change fixes a problem compiling the linux dynamic loader

Putting function labels (plabels) in the constant pool results
in a section flag conflict compiling rtld.c. Other targets don't

This patch to libgo provides the long double math functions if they are

done so that th

If the value of the DW_AT_high_pc is of class address, it is the

instruction associated with the entity; if it is of cl
