Specifically, I am seeing

what tells you that this is Leopard specific?
http://lists.apple.com/archives/darwin-dev/2007/Nov/msg00108.html
-optl-isysroot -optl/Developer/SDKs/MacOSX10.4u.sdk
-optl-mmacosx-version-min=10.4
Interesting, in contrast to you I had a problem with
-mmacosx-version-min and had to use MACOSX_DEPLOYMENT_TARGET when
building user programs on Leopard using my Tiger bindist.

I made a similar observation. Using -syslibroot in addition, fixed
the problem for me.
-optl-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk
on all CC and LD targets, I don't seem to have any Leopard symbols
anymore. FWIW, Xcode 3.0 also seem to use explicit SDK options.
I haven't built ghc on Leopard, yet, but I'll expect to use -isysroot
and -syslibroot then, too.
Hold off another day or two and you get that automatically by just
using --with-macos-deployment-target=10.4 with GHC's ./configure.
(This will even enable you to generate a GHC build for 10.4 from a
bootstrap compiler for 10.5, which is non-trivial due to the programs
in utils/ and some other stuff.)
