Hi,
This series adds minimalistic support for Memory Sanitizer (MSan) [1].
MSan is compiler instrumentation for detecting accesses to
uninitialized memory.
The motivation behind this is to be able to link elfutils into projects
instrumented with MSan, since it essentially requires all the code

clang complains:
asm_newscn.c:48:22: error: field 'pattern' with variable sized type 'struct
FillPattern' not at the end of a struct or class is a GNU extension
[-Werror,-Wgnu-variable-sized-type-not-at-end]
struct FillPattern pattern;

Fix by using a union i
clang complains:

Fix by deleting it.

__cxa_demangle is normally implemented in the C++ runtime library,
instrumenting which for MSan is a hassle. Add a knob for disabling it.

Add support for clang Memory Sanitizer [1], which detects the usage of
uninitialized values. While elfutils itself is already checked with
valgrind, checking code that depends on elfutils requires elfutils to
be built with MSan.
MSan is not linked into shared libraries, and is linked into
executab

On the low level, they are the same as pointers.

By default, clang produces .llvm_addrsig sections [1]. The GNU
toolchain does not know how to handle them yet [2], so just ask clang
not to generate them for the time being.
