fce38b7d13ae625301571dcd84f3774ddaa6ed04 c++: init_priority and SUPPORTS_INIT_PRIORITY [PR107638]
The commit r13-3706-gd0a492faa6478c for fixing the result of
__has_attribute(init_priority) causes a bootstrap failure on hppa64-hpux
due to assuming the macro SUPPORTS_INIT_PRIORITY expands to a simple
constant, but on this target the macro is defined as
#define SUPPORTS_INIT_PRIORITY (TARGET_GNU_LD ? 1 : 0)
(where TARGET_GNU_LD expands to something in terms of global_options)
which means we can't use the macro to conditionally exclude the entry
for init_priority when defining the cxx_attribute_table.
So instead of trying to exclude init_priority from the attribute table,
this patch just makes __has_attribute handle init_priority specially.
