3385ce92a2 * Always generate CFI-information. During linking it can be omitted when 
no debug-information is requested. On Linux this needed a change in the
   linker-script. On Windows it already works as desired. Other targets
   may need some adjustments as well.

9c088bda6a * fix for Mantis #36706: only link a library against the dynamic loader if we're not linking against the C library anyway 
Note: I did not yet find a case where we *do* need to link a library against the loader; this will have to be investigated further, but for 3.2.0 this is safest

6483b3f5e3 * fixed opt-in sysroot substitution again, renamed the three-argument version 
TSearchPathList.AddPath() to AddLibraryPath() to make it clear it's only
    to be used for adding library search paths (and replaced one case where
    it was used for a source file search path with a call to the
    two-argument version)
  * also added some missing '=' prefixes to built-in library search paths,
    and fixed wrong DirectoryExists checks in t_linux in case of using
    a sysroot, cross-compiling or linking on target

78fb35525f * change convention for searching sysroot library paths to be the same as the 
one used by GNU ld: only search for library paths in the sysroot if they
    are built into the compiler or start with "=". Previously, all
    user-provided library paths were also searched in the sysroot
    (mantis #36198)

fc60ec2ea4 + support for LLVM LTO: compile units with -CLflto -> when compiling a main 
program/library also with -Clflto, all units compiled with that option
    will be linked using their bitcode files and LTO
   o compiling with -CLflto will compile all units twice: once for normal
     (static or smart) linking, and once for LTO. So the result can be
     used both with and without LTO.
