how to build against an older SDK - library not found for -lcrt1.10.6.o

Hi, smart people.

I'm trying to write up a Portfile (for TenFourFox) that requires building against an older SDK (10.4u) and I'm on 10.6 Intel.

It's easy enough to pass in the sysroot

	configure.cxxflags-append -isysroot ${developer_dir}/SDKs/MacOSX10.4u.sdk
	configure.cflags-append -isysroot ${developer_dir}/SDKs/MacOSX10.4u.sdk
	configure.cppflags-append -isysroot ${developer_dir}/SDKs/MacOSX10.4u.sdk

but then the compiler errors out generating files due to a missing library that the compiler expects to see on 10.6, but doesn't exist in the 10.4u SDK.

configure:3576: /opt/local/bin/gcc-mp-4.8 -o conftest -Os -isysroot /Xcode3/SDKs/MacOSX10.4u.sdk -m64  -L/opt/local/lib -Wl,-headerpad_max_install_names  conftest.c  1>&5
ld: library not found for -lcrt1.10.6.o

I have a feeling this is not something fixable, other than maybe hacking a symlink for crt1.10.6.o into the 10.4u SDK (which is easy enough, but I'm trying to see if the can be done "the right way".

Any ideas?
