The flags I want to pass are -I, -L, -Wl,-R, and -Wl,--dynamic-linker,
so as to link to a glibc installed in a nonstandard directory. I've
just learned about C_INCLUDE_PATH, LIBRARY_PATH, etc., so I've set
those, and I've included the -Wl, options in CFLAGS, LDFLAGS, XCFLAGS,
TCFLAGS, STAGE1_CFLAGS, and BOOT_CFLAGS. Most things work, but unless
I use --enable-languages to exclude java, I get this error:

/package/host/localhost/glibc-2.2.5-1/lib/libc.so.6: undefined reference to `_dl_lazy@GLIBC_2.1.1'
...
So what Makefile variable do I need to set to include the -Wl, options
in that command?
