binutils-crosssdk: do not set .interp size to 0x1000 for partial linked objects
When building the SDK, the final .interp section size should be set to a
bigger value (0x1000) in order to be able to change the dynamic loader's
path later. However, we shouldn't do that for partial linked objects
(when -r or -rU is used). That's because those objects will then have an
.interp section of 0x1000 even if it contains no data and when the final
linking is done we will end up with a "cannot move location counter
backwards" error. That's because the linker will try to squeeze all the data in
the .interp sections found in various partial linked objects into one 0x1000
bytes final .interp section.
