Should ghci understand this pthread library?

[Maurí­cio CA]

After using ghci to load a library I'm working in, I got this
message:

   can't load .so/.DLL for: pthread (/usr/lib/libpthread.so:
   invalid ELF header)

Then I did 'cat /usr/lib/libpthread.so' and, much to my surprise,
it's a text file with the following contents:

   /* GNU ld script
      Use the shared library, but some functions are only in
      the static library, so try that secondarily.  */
   OUTPUT_FORMAT(elf32-i386)
   GROUP ( /lib/libpthread.so.0 /usr/lib/libpthread_nonshared.a )

Is this a standard file? Should ghci be able to understand it and,
maybe, use the listed libraries instead?

Thanks,
Maurício
