BTW; did you see what they did for ia64?

However, and elf32.em overrides what bfd puts in the .interp section:
emultempl/elf32.em: if test x"${ELF_INTERPRETER_NAME+set}" = xset; then
emultempl/elf32.em: sinterp->contents = ${ELF_INTERPRETER_NAME};
...
if (sinterp != NULL)
{
sinterp->contents = ${ELF_INTERPRETER_NAME};
sinterp->_raw_size = strlen (sinterp->contents) + 1;
}
elf32.em is used for both 32 and 64 bit elf.
I'm not saying what you did was wrong, but I am wondering out loud why the
existing mechanisms are not working. I noticed that there is an
elf64_sparc_fbsd.sh as well as elf64_sparc.sh, which does the same thing as
on ia64. Maybe the bmake glue isn't picking up the emulparms/*_fbsd.sh
versions? I know the ia64 gcc sets -dynamic-interpreter on the command
line so I suspect that if ld is misconfigured on ia64, it would be hidden
by this.
