Do not pollute libraries with its own implementation of __aeabi_unwind_cpp_pr1 code.
Just add it to uclibc_nonshared.a archive and share it.
This fixes build issue with static linking of application due to multiple symbol
definition in libgcc_eh-a and libpthread.a or librt.a

The double slash variants are not documented (doc bug?) so better use
the single slash variants like we usually do.

When built without NPTL support (or for a sparc target), the system()
function doesn't conform to its specification. Namely, it uses signal()
to install/save/restore signal handlers, which may break applications
using custom handlers installed with sigaction(). In addition, it resets
the SIGCHLD handler to SIG_DFL instead of blocking the signal, which may
result in "lost" signals if a custom handler was installed.
Fix system() by replacing uses of signal() with appropriate calls to
sigaction() and sigprocmask().

As suggested by Bernhard, there is no point in evaluating the compiler's
flag availability when cleaning, so skip things in that case. If there
are variables that change targets based on the flags, then things are
already broken and need fixing independently.

Since we want to clean out all the headers we symlinked into include/,
just use `find` to locate all the symlinks for us. This simplifies it
greatly, and actually fixes bugs where we build for one arch, switch
to another, and then do a clean but the previous arch headers are left
behind.

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’.

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).
