It sounds like I might have misunderstood your question.  I thought you
were asking whether there was any way the kernel could handle init/fini
arrays itself, rather than leaving it to the crt code.  (And it would
have to be the kernel because, as you say, there's no separate loader
involved here.)

Are you asking instead whether normal .init_array and .fini_array
sections are handled by the patch as-is?  If so, the answer's yes.
It handles both .init/.fini sections and .init_array/.fini_array
sections, much as __uClibc_main.c already does for "static"
uClinux executables.
