Dmitry Smirnov 8b682d167e prioritise use of `javac` executable (gcj provides it through alternatives).
On Debian this fixes FTBFS when gcj-jdk and openjdk-7-jdk are installed at
 the same time because build system will use default `javac` executable
 provided by current JDK through `update-alternatives` instead of blindly
 calling GCJ when it is present.

Loic Dachary 399de24e29 erasure-code: do not attempt to compile SSE4 on i386
SSE4 are only not availabe on older CPUs. Although the compiler could
probably generate the code, there is no point in doing so. The SSE4.1,
SSE4.2 and PCLMUL cpu features are only tested if the target CPU is
AMD64 or x86_64.

Loic Dachary c07aedb6db autotools: intel cpu features detection
Rename SIMD to INTEL for clarity.

Instead of agregating all flags in INTEL_FLAGS, create individual flags
for each feature (INTEL_SSE2_FLAGS etc.) for finer control in the
makefiles.

Loic Dachary 8c7f6c11d4 autotools: AX_SSE detects the compiler SSE capabilities
For each SSE feature supported by the compiler

* add the corresponding -msse* flag
* define HAVE_SSE*

Remove AX_EXT because it decides based on the CPU capabilities of the
machine compiling the binary which may or may not be the one running
them.

Noah Watkins ac044812d0 assert: choose function-var name on non-gnu
Selects __PRETTY_FUNCTION__ or __func__. Linux assumes GNU, and chooses
__PRETTY_FUNCTION__ if gcc/g++ versions are favorable.

This also includes a fix in ax_c_var_func.m4:

AC_TRY_COMPILE will wrap the test in main{}, and then GCC will complain
about nested functions. Just use the original main{} body.

Danny Al-Gaaf 59aad34795 configure.ac: check for org.junit.rules.ExternalResource
Check for org.junit.rules.ExternalResource if build with
--enable-cephfs-java and --with-debug. Checking for junit4
isn't enough since junit4 has this class not before 4.7.

Added some m4 files to get some JAVA related macros. Changed
autogen.sh to work with local m4 files/macros.
