When building a uClibc toolchain for crisv32-linux ld is segfaulting.           
I git bisected binutils and the faulty commit is the following                  
Binutils 2.29.1 is the last workinng released version.

    cris: Check UNDEFWEAK_NO_DYNAMIC_RELOC                                      

    Don't generate dynamic relocation against weak undefined symbol if it       
    is resolved to zero.  FIXME: UNDEFWEAK_NO_DYNAMIC_RELOC may need to be      
    checked in more places.

            * elf32-cris.c (cris_elf_relocate_section): Don't generate          
            dynamic relocation if UNDEFWEAK_NO_DYNAMIC_RELOC is true.           
            (cris_elf_check_relocs): Don't allocate dynamic relocation          
            if UNDEFWEAK_NO_DYNAMIC_RELOC is true.                              

    ld/                                                                         

            PR ld/22269                                                         
            * testsuite/ld-cris/weakhiddso.d: Update and remove R_CRIS_NONE.

I couldn't find a simple test case, it happens when ld.so is linked together.
