Could be that. I think I don't have an incentive to go
investigate that, though.

Point was, what's after doesn't matter, as libgcc{,_eh} would be
before uclibc in the search path (unless botched by manual
-nostdlib intervention :)
...but since the __aeabi_unwind_cpp_pr1 symbol in libgcc_eh and
libgcc_s is weak and the one in uclibc is (hidden but) strong,
it doesn't matter. Oh well.
Thanks for your time.
