I have filed a bug report on this one. My code passes all its tests,
notwithstanding the warning, so I hope the matter is inconsequential.
I think the error message refers to the flags with which the cited
library, "/Developer/SDKs/MacOSX10.4u.sdk/usr/lib/crt1.o", was
compiled.

Same here. Using gcc 4.0, 10.4u SDK.
Same for me. It's a universal binary, and the message only appears
when linking the PPC version. Browsing the compile flags, there's no
sign that -mlong-branch was actually used.
I thought it might have something to do with my custom CFLAGS (that it
was implicitly enabled by something I had added) but removing them had
no effect.
This message only appears when compiling a release build, so I suspect
it's a side-effect of optimization settings or some other difference
between that build and a debug build. I'll keep investigating...
