Subject: [PATCH] a libraries paths

    * x86_64-tcc: use /usr/lib64,.. instead of /usr/lib,..
    * don't set tcc_lddir="lib64" if cpu="x86"
    * put a definition of the CONFIG_LDDIR into config.h instead
      of the config.mak  Otherwise a "lib" string may be used by default.
      This is a usual case when building a x86_64-tcc (there was
      no -DCONFIG_LDDIR building this binary).

    * suppress -Wdeprecated-declarations for gcc which complain on malloc hooks
      in bcheck.c if glibc is quite new.
