Description of problem:
The libtool file generated on Linux doesn't work on Irix when compiling a
library written in standard C++.

To compile such a library on Irix, you have to pass the flag -LANG:std to the
compiler and the linker.  But libtool thinks that that flag specifies a path to
search for libraries.

This is a known problem, and in libtool there is an attempt to fix it:

      # The native IRIX linker understands -LANG:*, -LIST:* and -LNO:*
      # so, if we see these flags be careful not to treat them like -L
      -L[A-Z][A-Z]*:*)
        case $with_gcc/$host in
        no/*-*-irix*)
          compile_command="$compile_command $arg"
          finalize_command="$finalize_command $arg"
          ;;

The problem is that earlier in the libtool file with_gcc is defined as blank,
instead of defined as "no":

# Is the compiler the GNU C compiler?
with_gcc=


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. write a standard C++ library
2. create a tarball on Linux
3. try to compile the library on Irix
    

Actual Results:  The linking phase will fail because the -LANG:std flag is not
passed correctly to the linker.

Expected Results:  libtool should have defined with_gcc=no.

Additional info:

If you change libtool so that with_gcc=no, then the linking phase succeeds.
