[U-Boot] [PATCH] kbuild: fix SPL link bug when USE_PRIVATE_LIBGCC is "yes"

[Masahiro Yamada]

Commit 6825a95 (kbuild: use Linux Kernel build scripts)
changed the behavior of linkage when USE_PRIAVATE_LIBGCC
is defined as "yes".
(It dropped arch/arm/lib/eabi_compat.o from the
target library.)

Affected boards are all Tegra boards.

This commit gets back the same behavior as before Kbuild series.
