added libraries: opus flac libsndfile updated: libvorbis libogg openal - Everything works as expected for now. Bare in mind libsndfile needed the check for whether or not it could find the xiph libraries removed in order for this to work.

dnl
|
|
dnl Determine endian-ness of target processor.

dnl @author Erik de Castro Lopo <erikd@mega-nerd.com>

dnl
|
|
dnl Majority written from scratch to replace the standard autoconf macro
|
|
dnl AC_C_BIGENDIAN. Only part remaining from the original is the invocation
|
|
dnl of the AC_RUN_IFELSE([AC_LANG_SOURCE([[]])],[],[],[]) macro.
|
|
dnl
|
|
dnl Find endian-ness in the following way:
|
|
dnl 1) Look in <endian.h>.
|
|
dnl 2) If 1) fails, look in <sys/types.h> and <sys/param.h>.
|
|
dnl 3) If 1) and 2) fails and not cross compiling run a test program.
|
|
dnl 4) If 1) and 2) fails and cross compiling then guess based on target.
