Tidy bfd_scan_vma

Tidy bfd_scan_vma

[Alan Modra]

In commit 83c79df86bf4 I removed configure tests for strtoull among
other library functions part of C99, but didn't remove what is now
dead code.

	* bfd.c (bfd_scan_vma): Delete fall-back for strtoull.

 	bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
 
 DESCRIPTION
-	Convert, like <<strtoul>>, a numerical expression
-	@var{string} into a <<bfd_vma>> integer, and return that integer.
-	(Though without as many bells and whistles as <<strtoul>>.)
-	The expression is assumed to be unsigned (i.e., positive).
-	If given a @var{base}, it is used as the base for conversion.
-	A base of 0 causes the function to interpret the string
-	in hex if a leading "0x" or "0X" is found, otherwise
-	in octal if a leading zero is found, otherwise in decimal.
-
-	If the value would overflow, the maximum <<bfd_vma>> value is
-	returned.
+	Convert, like <<strtoul>> or <<stdtoull> depending on the size
+	of a <<bfd_vma>>, a numerical expression @var{string} into a
+	<<bfd_vma>> integer, and return that integer.
