[RFC] Fix PR target/20301

[Eric Botcazou]

Hi,

The submitter of this PR managed to cause the compiler to emit labels with 
negative index numbers (big jar file, >= 2^31 labels) on SPARC/Solaris.
The problem stems from:

 #define ASM_GENERATE_INTERNAL_LABEL(LABEL,PREFIX,NUM)	\
  sprintf ((LABEL), "*.L%s%ld", (PREFIX), (long)(NUM))

on Solaris.  A quick grep shows that most macros use the signed version, while 
the others do use the unsigned one which seems more correct to me.  Any 
specific reason for the discrepancy?

Tested SPARC/Solaris 2.5.1 up to 10.
