I have no idea what you original problem may be but your linker reported:
"no memory region specified for loadable section `.plt'"

It seems that the arm-gcc generated that code under certain conditions. It has nothing
with the files you use but with the options you/busybox use.
e.g. "Warning: gc-sections option ignored"

As allways with debugging
0. check you toolchain when crosscompiling ( does hello "word" work ?)
1. reduce the number of options (you can get the ld commandline with gcc -v), and reduce one by one
2. make an educated guess what the problem actualy is (ask google,yahoo, what ever)

Sometimes we can see what the error might be, sometime we can only point in a direction.
