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> ])], ...)
