qversiontagging: merge the qt_version_tag symbols
The symbols all still exist, but they all have the same address. For
example, in my Linux debug build:
$ eu-readelf --dyn-syms lib/libQt6Core.t.so | grep qt_version_tag
4352: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag_6_0@@Qt_6
4356: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag_6_1@@Qt_6
4358: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag_6_2@@Qt_6
4362: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag_6_3@@Qt_6
4364: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag_6_4@@Qt_6
6458: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag@@Qt_6.4
6460: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag@Qt_6.0
6462: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag@Qt_6.2
6463: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag@Qt_6.3
6466: 00000000005e3e74 1 OBJECT GLOBAL DEFAULT 18 qt_version_tag@Qt_6.1
(The part after the @ is the ELF version; two @ indicates the default
version)
Saves N bytes where N is the Qt minor version number. The exclusion of
Darwin (macOS) is because clang says that it has the "alias" attribute,
but then fails when you use it.
