Description:
Linux systems have different filesystem layouts depending on few things.

http://www.pathname.com/fhs/ defines three possible cases:
/usr/lib/ (typical 32 bit system)
/usr/lib64 (64 bit system)
/usr/lib32 (some 64 bit systems)

For details see http://www.pathname.com/fhs/pub/fhs-2.3.html#LIB64

How to repeat:
less configure.in

Suggested fix:
--- configure.in.org    2007-07-09 21:02:00.433589939 +0200
+++ configure.in        2007-07-09 21:02:16.877766255 +0200

 if test "$TARGET_LINUX" = "true" -a "$static_nss" = ""
 then
-  tmp=`nm /usr/lib/libc.a  | grep _nss_files_getaliasent_r`
+  tmp=`nm /usr/lib*/libc.a  | grep _nss_files_getaliasent_r`
   if test -n "$tmp"
   then
      STATIC_NSS_FLAGS="-lc -lnss_files -lnss_dns -lresolv"

Better than current one but not perfect (since in rare ocassions there can be both - 32bit and 64bit libc.a installed at the same time).

  Allow for different directories containing the "libc",
  as it may well happen with 32- vs 64-bit Linux systems.
