        c: Update TLS model after processing a TLS variable
    
        Set a tentative TLS model in grokvardecl and update TLS mode with
        the default TLS access model after a TLS variable has been fully
        processed if the default TLS access model is stronger,
    
    triggered a linker error when building glibc using build-many-glibcs.py.
    
    See: https://sourceware.org/pipermail/binutils/2025-September/144225.html
    
    This fix uses more appropriate assertions.
    
    (cherry picked from commit 87961e47c3666d0527b8ce60e56617e63db0a6c4)
