complibs: better deduce whether to backup complibs or not

To decide whether we need to backup the companion libraries,
do not rely on the !shared case. In the future other cases
may require not to save the companion libraries (eg. if using
the ones provided by the host distro).

     1 Original patch from Gentoo.

     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.
