[PATCH] fix PLTJMP macro in libc/sysdeps/linux/sh/clone.S

[Carmelo Amoroso]

Hi,
compiling the uClibc (svn) for sh4 it stops with the following 
preprocessing error:

"
libc/sysdeps/linux/sh/clone.S:122:1: error: pasting ")" and "@" does not 
give a valid preprocessing token
  .long __GI__exit at PLT
.size clone,.-clone;
"

even if the offending macro PLTJMP(HIDDEN_JUMPTARGET(_exit)) seems to be
correctly expanded.

Simply removing the past ## token from the PLTJMP macro definition, it 
works. (anyway the reason for which it was failing is not still clear to 
me, any tips?)

Please, find attached the related patch.

Regards,
Carmelo
