build-sys: fix AC_COMPILE_IFELSE tests
This removes some warnings when bootstrapping. The warnings were introduced
in autoconf 2.68. Reference:
http://www.flameeyes.eu/autotools-mythbuster/forwardporting/autoconf.html
The following code
AC_COMPILE_IFELSE([
<MY C CODE HERE>
], ...)
is changed to
AC_COMPILE_IFELSE(
[AC_COMPILE_IFELSE([AC_LANG_SOURCE([
<MY C CODE HERE>
])], ...)
