However Apple[1] tells LDFLAGS="-arch i386 -arch ppc",
but the same thing of the note about CFLAGS for PPC may be true too for
LDFLAGS al least in the case of dynamic lib.
The same is for libiconv, so if it's the right way it maybe better
change directly the line "default configure.universal_ldflags ..." in
/opt/local/share/macports/Tcl/port1.0/portconfigure.tcl.
PS: It works too with "-L/Developer/SDKs/MacOSX10.4u.sdk/usr/lib"
instead of "-isysroot /Developer/SDKs/MacOSX10.4u.sdk".

I found this old thread:

http://lists.apple.com/archives/unix-porting/2005/Oct/msg00004.html
So it seems that it's ok to pass -syslibroot to ld trought
-Wl,-syslibroot or -isysroot in LDFLAGS, but only if the makefile
doesn't pass CFLAGS (where -isysroot is already present) for linking.
