Maybe, but the manual is very clear:
`-pie'
Produce a position independent executable on targets that support
it. For predictable results, you must also specify the same set
of options used for compilation (`-fpie', `-fPIE', or model
suboptions) when you specify this linker option.
so one could argue that it's up to the user to check that it works on a given
platform.

He's using the Sun tools and you're using the GNU binutils, so this may
primarily be a binutils issue. Does it work with the Sun tools on your
machine?
