Tests/Assembler: Drop -g when generating sample assembly source

Some compilers, such as Clang on OS X, do not want the -g flag for both
generating assembly code and assembling it.  Drop the -g flag from
generation of main.s in the Assembler test.
CPack: Disable OS X PackageMaker by default (#13662)

As mentioned in commit 4693cf84 (Xcode: Detect new default locations of
Xcode 4.3 bits and pieces) PackageMaker was split out of Xcode 4.3 and
above into a separate Auxiliary tools package.  Since Xcode 5.0 or so,
Apple no longer distributes PackageMaker as part of the available
development tools so it can only be obtained from old packages.

Disable the CPACK_BINARY_PACKAGEMAKER option by default as is the case
for most other tool-dependent generators.

FindPHP4: Drop extra content from reported PHP4_INCLUDE_PATH (#14540)

The set() call for this variable left out the CACHE keyword.  It does
not need to be cached anyway, so drop the other CACHE set() signature
arguments.

FindJNI: Support biarch installations (#14541)

On biarch architecture, CMAKE_SYSTEM_PROCESSOR might be a 64bit one
while the system 32bit one. Take this into consideration while looking
for Java library directory.
