- fix incorrect setting of $ac_cv_sys_symbol_underscore.

  There is no reason not to AC_COMPILE and use the set cross-nm to look for
  the symbol mangling scheme. Thus it is incorrect to check for cross compilation
  in the GNUPG_SYS_SYMBOL_UNDERSCORE check.
- fix bug when configuring (has to wipe config.cache !)
