Questions about RedHat/Fedora - ld dynamic linker hash style

[Kelly O'Hair]

I need some advice or information, figured this alias might be the
right place to ask, probably lots of gcc/ld experts listing in here. ;^)

Fedora (RedHat?) seems to have a different default dynamic linker hash style,
I think basically it is:
    ld --hash-style=gnu ..

So without using one of:
   --hash-style=both or --hash-style=sysv

The bits created won't run on systems that don't support this new hash
style, like SuSE 10.

We had planned on changing our formal JDK7 builds to Fedora 9 but
ran into this problem, making our built bits less portable than we
would like. We need to resolve this, or change our build system
choice.

I'd like to just add one of the options to the link lines in the
OpenJDK Makefiles, but I suspect I need to be careful to only add
the option when the Linux system doing the build needs it.

Anybody have any ideas on how to deal with this?
I suppose if we had a './configure' step it could be figured out
there, but alas, we don't.

Or, can you configure gcc/ld on a system to have a different default
hash style?
