    loongarch: add back support for object attributes v1
    
    A previous commit [1] mistakenly removed support for Object Attributes
    for LoongArch targets.
    
    This patch adds back the OA feature into Gas for the LoongArch targets
    following the new approach which consists in:
    - defining TC_OBJ_ATTR to 1 in tc-loongarch.h
    - enabling the compilation of obj-elf-attr.c in gas/configure.ac
    
    [1]: 28a51085ae59fdb530fbdce1e2a7d160667e3007
