ld: Make separate clauses where a label was before a declaration

ld: Make separate clauses where a label was before a declaration

The default behavior of gcc changed from gcc-11.  With gcc-10 and
earlier versions, you got:

In file included from ../bfd/bfd.h:45,
                 from /src/ld/ldmisc.c:23:
/src/ld/ldmisc.c: In function 'vfinfo':
/src/ld/ldmisc.c:186:8: error: a label can only be part of a statement and a declaration is not a statement
  186 |        bool ll_type = false;
      |        ^~~~
/src/ld/ldmisc.c:581:8: error: a label can only be part of a statement and a declaration is not a statement
  581 |        bool ll_type = false;
      |        ^~~~
make[4]: *** [Makefile:1606: ldmisc.o] Error 1

Since gcc-10 matches the binutils/README requirement ("a C99 compliant
compiler and library") and as binutils policy is to adjust code to
handle earlier gcc versions, an obvious fix is to make a compound
statement for the code after the case-label.

ld:

	* ldmisc.c (vfinfo) <case 'l' - two cases>: Make separate
	compound statements where case-labels were part of a declaration.
