The MAKEFLAGS variable contains all the flags without the leading dash.
From the GNU make manual:
This variable is set up automatically by make to contain the flag
letters that make received. Thus, if you do ‘make -ks’ then MAKEFLAGS
gets the value ‘ks’.

We inherit the top-level Rules.mak which sets up this flag for us,
so just rely on that.

If backtrace support is turned on, build raise() and abort() with
unwind info (fixup 4c9b7f3c21ff21c199e54bfad2fdf3445fa4573d).

Invalid signals have no handlers so when trying to restore the old
handler to a bad signal a SIGSEGV occurs. This is because the library
tries to store the old handler to an invalid memory area where it things
the bad signal lives.

Running `make clean` atm takes like 20 seconds because every subdir
re-evaluates all the toolchain flags. Add some helpers to automate
the process of setting up variables to cache the result of tests,
as well as the checking of an already set flag.
Now `make clean` takes like 2 seconds on my system.

From gcc documentation, we can read:
" ...
-fasynchronous-unwind-tables
Generate unwind table in dwarf2 format, if supported by target
machine. The table is exact at each instruction boundary, so it can be
used for stack unwinding from asynchronous events (such as debugger or
garbage collector)
..."
So it seems better rather than using -funwind-tables (glibc seems to prefer
-fasynchronous-unwind-tables).

Build raise and abort function with dwarf2 info by using
-fasynchronous-unwind-tables to make backtrace() working across a
call to abort.
A scenario where it could be useful is within a signal handler that
wants to dump a backtrace when catching some signal (i.e SIGABRT).
Without having abort & raise built with DWARF2 information, it is not
possible for the libgcc stack unwinder to walk through the call stack
out of the abort/raise function.
Impacts in terms of size are really limited

If people use an interp path such as "ld.so", then there is no "/" found,
and we end up dereferencing a NULL pointer. Simplify the logic by having
a relative interp path like that be the same as "" (which the code later
on interprets as $PWD).
While we're here, document some of the nuances of this code.

This is based on Ulrich Drepper's implementation in GLIBC, but hacked up to work
in uClibc. The differences from the GLIBC version are as follows:
- b64_from_24bit() has been converted into a macro
- Usage of GLIBC-isms (such as libc_freeres_ptr) have been removed
It is enabled by the UCLIBC_HAS_SHA256_CRYPT_IMPL configuration symbol. You must
have UCLIBC_HAS_CRYPT_IMPL enabled as well.

This implements big-dlfcn lock to allow multithreaded usage of
dlopen/dlsym/dlclose. We should really clean up the dl code so
we can use more fine grained locking or even RCU where appropriate.
But at least we won't crash now.
