Support for ELF's STT_COMMON symbol type

[Nick Clifton]

Hi Guys,

   Here is a revised patch which I think is suitable for checking in, but I 
would like to hear from anyone who disagrees or has any concerns.  This version 
of the patch:

   * Has a configure time option to enable the setting of the STT_COMMON type 
on symbols in generated executables.  By default this option is disabled, so 
the linker should continue to work with the current crop of loaders.

   * The assembler now checks to see if the .type pseudo-op is being used to 
make an already defined symbol into a common, and if so it issues an error 
message and ignores the request.

   * I have added some extra tests to the linker testsuite to cover linking 
with -static, -shared, -r, and -pie.

Comments ?

Cheers
   Nick
