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).

Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr> 
     1 GCC trunk now has multiple internal headers directories, one

     2 containing the self-contained GCC-provided headers and one containing

     3 the <limits.h> (not self-contained but including libc's <limits.h> or

     4 a fixed version thereof) and the fixed headers; more such directories

     5 may be added in future.

     6 

     7 When glibc uses -nostdinc, it needs to use -isystem options for all

     8 these internal directories.  This patch teaches it about the

     9 include-fixed directory (and is harmless with old GCC versions without

    10 that directory).

    14 	* configure.in: Also pass -isystem option for GCC's include-fixed

    15 	directory.

    16 	* configure: Regenerate.
