stray stderr output for cat: /etc/ld.so.conf.d/*.conf:

[Brian Gough]

Hello,

On SUSE 9.3 and SUSE 10 I'm noticing stray error messages in configure
output coming from AC_LIBTOOL_SYS_DYNAMIC_LINKER in libtool-1.5.22 and
earlier.  Probably this has been reported before....

Example:

   checking whether -lc should be explicitly linked in... no
   checking dynamic linker characteristics... cat: /etc/ld.so.conf.d/*.conf: No 
such file or directory
   GNU/Linux ld.so
   checking how to hardcode library paths into programs... immediate

On these systems /etc/ld.so.conf contains the line

  include /etc/ld.so.conf.d/*.conf

but /etc/ld.so.conf.d/ is typically empty so the expansion fails.
Maybe it is worth redirecting stderr for the 'cat %s' below to
/dev/null to hide the error?
