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 This patch is needed on newer uclibc becuase the uclibc header generation
     2 mechanism generates the sysnum.h properly NR_cacheflush is defined for ARM
     3 but there is no cachectl.h file which is exported to userspace. Strace 
     4 assumes that if SYS_cacheflush is defined than it icludes asm/cachectl.h
     5 which breaks the build for ARM now.

     7 This patch adds a check for ARM architecture.
