I'm not sure. My guess is that if someone is using sufficiently
recent gcc and binutils then it will be ok... i.e. if they're using a
recent enough gld then it will grok "-h", and also if they're using
the native linker it will dtrt. If they're using gcc and a gld that's
old enough to not know about "-h" then we might have a problem, but
I'm not sure we want to worry about supporting that... esp since we'd
have to test the following, basically in order:
* does gcc accept "-h"
(I'm not sure when this showed up in gcc... possibly 2.7.0)
* does gcc accept "-Wl,-h -Wl,libfoo.so.0.0"
(This means that the linker called by gcc will take "-h")
* does gcc accept "-Wl,-soname -Wl,libfoo.so.0.0"
(This means we're using the gnu ld, and it takes "-soname")
I'm not certain that it's worth the bother.
