commit bc2d5715f687098b8cd66cf5c90e3f472ad0788f
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>

    Remove argp-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.
