GCC: Check if AR works with --plugin and rc
AR from older binutils doesn't work with --plugin and rc:

[hjl@gnu-cfl-2 bin]$ touch foo.c
[hjl@gnu-cfl-2 bin]$ ar --plugin /usr/libexec/gcc/x86_64-redhat-linux/10/liblto_plugin.so rc libfoo.a foo.c
[hjl@gnu-cfl-2 bin]$ ./ar --plugin /usr/libexec/gcc/x86_64-redhat-linux/10/liblto_plugin.so rc libfoo.a foo.c
./ar: no operation specified
[hjl@gnu-cfl-2 bin]$ ./ar --version

Check if AR works with --plugin and rc before passing --plugin to AR and
RANLIB.

The libbacktrace library
Initially written by Ian Lance Taylor <iant@golang.org>

The libbacktrace library may be linked into a program or library and
used to produce symbolic backtraces.
Sample uses would be to print a detailed backtrace when an error
occurs or to gather detailed profiling information.
In general the functions provided by this library are async-signal-safe,
meaning that they may be safely called from a signal handler.

The libbacktrace library is provided under a BSD license.
See the source files for the exact license text.

The public functions are declared and documented in the header file
backtrace.h, which should be #include'd by a user of the library.

Building libbacktrace will generate a file backtrace-supported.h,
which a user of the library may use to determine whether backtraces
will work.
See the source file backtrace-supported.h.in for the macros that it
defines.

As of October 2020, libbacktrace supports ELF, PE/COFF, Mach-O, and
XCOFF executables with DWARF debugging information.
In other words, it supports GNU/Linux, *BSD, macOS, Windows, and AIX.
The library is written to make it straightforward to add support for
other object file and debugging formats.

The library relies on the C++ unwind API defined at
https://itanium-cxx-abi.github.io/cxx-abi/abi-eh.html
This API is provided by GCC and clang.
