    lto, Darwin: Fix offload section names.
    
    Currently, these section names have wrong syntax for Mach-O.
    Although they were added some time ago; recently added tests are
    now emitting them leading to new fails on Darwin.
    
    This adds a Mach-O variant for each.
    
    gcc/ChangeLog:
    
            * lto-section-names.h (OFFLOAD_SECTION_NAME_PREFIX,
            OFFLOAD_VAR_TABLE_SECTION_NAME, OFFLOAD_FUNC_TABLE_SECTION_NAME,
            OFFLOAD_IND_FUNC_TABLE_SECTION_NAME): Provide Mach-O syntax
            versions when the object format is Mach-O.
