Nasty stuff.

const struct LparMap __attribute__((__section__(".text"))) xLparMap = {

This will declare the .text section as non-executable.  Whoops.

Another way around this, which is perhaps a bit hacky but
doesn't require your post-processing, is to use

__section__(".text #")

which will cut off the compiler-generated "a" (where the assembler
wants "ax", which is the default)  :-)
