configure: Replaced obsolete AC_TRY_COMPILE

Browse Source 
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
