Previously with archive libraries fdt.o was compiled and included in
qe.a and then discarded by the linker. With partial linking this
results in unresolved symbols, which this commit fixes.
This commit also cleans up a now-useless conditional in fdt.c.

The size increase you noted seems to completely go away when adding
--gc-sections to LDFLAGS, but this option apparently brings its own
issues when the linke

This commit reveals board configurations that exclude some module but not all
of its dependencies; for
example, disabling CMD_NET but not CMD_NFS results in undefined symbols at link
time.

config_checks.h be an ok name for it? I suppose there might be other

Partial linking with ld -r ? That does seem like a fairly simple change.

I am trying to get the ELF relocation working with the arm920t, and I
have applied the patch recently posted to the list by Andreas

I found that adding these two sections to the linker script gets rid
of both assert failures:
.plt : { *(.plt) }
.rel.plt : { *
