libc/uClibc: move content of do_libc_headers into do_libc_start_files

It is unnecessary to split C library preparation into two steps, as only
one really makes sense. So, do_libc_headers is bound to be withdrawn
short-term, in favor of do_libc_start_files.

uClibc already had all its start files installation in do_libc_headers, and
do_libc_start_files was empty, just migrate the content of the former into
the latter.

     4 ARMV5 can use STRD and LDRD access instructions but these accesses need to be 

     5 8 byte aligned. The dynamic linker's malloc needs to match this so structures

     6 become 8 byte aligned to void unaligned accesses.
