ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

objtool: Add more robust signal error handling, detect and warn about stack overflows

When the kernel build fails due to an objtool segfault, the error
message is a bit obtuse and confusing:

make

objtool: Add more robust signal error handling, detect and warn about stack overflows

When the kernel build fails due to an objtool segfault, the error
message is a bit obtuse and confusing:

make[5]: *** [scripts/Makefile.build:503: drivers/scsi/qla2xxx/qla2xxx.o] Error 139
^^^^^^^^^
make[5]: *** Deleting file 'drivers/scsi/qla2xxx/qla2xxx.o'
make[4]: *** [scripts/Makefile.build:556: drivers/scsi/qla2xxx] Error 2
make[3]: *** [scripts/Makefile.build:556: drivers/scsi] Error 2
make[2]: *** [scripts/Makefile.build:556: drivers] Error 2
make[1]: *** [/home/jpoimboe/git/linux/Makefile:2013: .] Error 2
make: *** [Makefile:248: __sub-make] Error 2

Add a signal handler to objtool which prints an error message like if
the local stack has overflown (for which there's a chance as objtool
makes heavy use of recursion):

drivers/scsi/qla2xxx/qla2xxx.o: error: SIGSEGV: objtool stack overflow!

or:

drivers/scsi/qla2xxx/qla2xxx.o: error: SIGSEGV: objtool crash!

Also, re-raise the signal so the core dump still gets triggered.

[ mingo: Applied a build fix, added more comments and prettified the code. ]
