Complete rework of makefile generators expect trouble

IF(CMAKE_SYSTEM MATCHES "SunOS-4.*")
Add platform variables for position independent code flags Store in new platform variables CMAKE_${lang}_COMPILE_OPTIONS_PIC CMAKE_${lang}_COMPILE_OPTIONS_PIE flags for position independent code generation. In almost all cases, this means duplication of the CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the assumed pie equivalent for the _PIE case. Note that the GNU compiler has supported -fPIE since 3.4 and that there is no -fPIC on GNU for Windows or Cygwin. There is a possibility that the _PIE variables are not correct. However, as there is no backwards compatibility to be concerned about (as the POSITION_INDEPENDENT_CODE property is not used anywhere yet), the current state suffices.

BUG: Don't use -nostdlib option to link shared libraries. Just use gcc -shared, even for C++ libraries.

Support building shared libraries or modules without soname (#13155) Add a boolean target property NO_SONAME which may be used to disable soname for the specified shared library or module even if the platform supports it. This property should be useful for private shared libraries or various plugins which live in private directories and have not been designed to be found or loaded globally. Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and hard-coded -install_name flags with a conditional <SONAME_FLAG> which is expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG definition as long as soname supports is enabled for the target in question. Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in rules in case third party projects still use it. Such projects would not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be expanded. Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well. Since -install_name is soname on OS X, this should not be a problem if this variable is expanded only if soname is enabled. The Ninja generator performs rule variable substitution only once globally per rule to put its own placeholders. Final substitution is performed by ninja at build time. Therefore we cannot conditionally replace the soname placeholders on a per-target basis. Rather than omitting $SONAME from rules.ninja, simply do not write its contents for targets which have NO_SONAME. Since 3 variables are affected by NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if soname is enabled.

ENH: Enable dependent library search paths on more platforms - HP-UX needs dependent library paths as -L options. - IRIX needs dependent library paths as -L options. - Sun needs dependent library paths as -L options. - FreeBSD needs dependent library paths in -rpath-link option.

ENH: Better linker search path computation. - Use linker search path -L.. -lfoo for lib w/out soname when platform sets CMAKE_PLATFORM_USES_PATH_WHEN_NO_SONAME - Rename cmOrderRuntimeDirectories to cmOrderDirectories and generalize it for both soname constraints and link library constraints - Use cmOrderDirectories to order -L directories based on all needed constraints - Avoid processing implicit link directories - For CMAKE_OLD_LINK_PATHS add constraints from libs producing them to produce old ordering
