    PR ld/20828: Relax symbol ordering in tests

    Complement commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols
    wrongly forced local with section GC") and make tests check for the
    presence of global `_fdata' and `_edata' symbols separately, removing
    any dependency on symbol table ordering for tests to succeed and
    removing:

    FAIL: PR ld/20828 dynamic symbols with section GC (auxiliary shared
library)
    FAIL: PR ld/20828 dynamic symbols with section GC (plain)

    failures with the `x86_64-solaris2' target, which has additional
    intervening entries:

    Symbol table '.dynsym' contains 6 entries:
       Num:    Value          Size Type    Bind   Vis      Ndx Name
         0: 0000000000000000     0 NOTYPE  LOCAL  DEFAULT  UND
         1: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT    1 _fdata
         2: 0000000000000000     0 OBJECT  GLOBAL DEFAULT    1 _DYNAMIC
         3: 0000000000000000     0 OBJECT  GLOBAL DEFAULT  ABS
_PROCEDURE_LINKAGE_TABLE_
         4: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT    1 _edata
         5: 00000000000001b8     0 OBJECT  GLOBAL DEFAULT    4
_GLOBAL_OFFSET_TABLE_

    Rename dump pattern files accordingly for consistency.
