Yes, it is a somewhat known culprit. A number of packages that are
messing with assembly code have troubles due to this directive. The
better way to overcome this issue is not to patch linker scripts, but to
override object format via '--oformat elf32-i386-freebsd' command-line
switch to ld(1). With this your proposed patch could be made even
smaller, providing that you can override linker command-line switches,
and it will be more robust in respect to the patching troubles when
linker scripts will be changed.
