Libtool can't find libgcc_s

[ethan . mallove]

Hi,

Libtool seems to get confused about where libgcc_s is, e.g.,
  
  $ /bin/sh ../../../libtool --tag=CXX --mode=link icpc -lgcc_s foo.c -o a.out
  libtool: link: icpc foo.c -o a.out  -lgcc_s
  ld: skipping incompatible /usr/lib/gcc/x86_64-redhat-linux/3.4.6//libgcc_s.so 
when searching for -lgcc_s
  ld: cannot find -lgcc_s

If I help it out with my own -L, it works:

  $ /bin/sh ../../../libtool --tag=CXX --mode=link icpc 
-L/usr/lib/gcc/x86_64-redhat-linux/4.1.2/32 -lgcc_s foo.c -o a.out
  libtool: link: icpc foo.c -o a.out  
-L/usr/lib/gcc/x86_64-redhat-linux/4.1.2/32 -lgcc_s

  $ ../../../libtool --version
  ltmain.sh (GNU libtool) 2.2.6b

What's going on?
