This patch replaced obsolete AC_TRY_COMPILE to AC_COMPILE_IFELSE or AC_PREPROC_IFELSE. It has been confirmed that GNU 'autoconf' 2.69 suppressed obsolete warnings, updated the following files: - configure - sysdeps/mach/configure - sysdeps/mach/hurd/configure - sysdeps/s390/configure - sysdeps/unix/sysv/linux/configure and didn't change the following files: - sysdeps/ieee754/ldbl-opt/configure - sysdeps/unix/sysv/linux/powerpc/configure Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
