Benoit Daloze 0a5d9828c1 Make the gem build on TruffleRuby (#27660)
* replace darwin checks in extconf.rb to exclude TruffleRuby

* inherit RANLIB and STRIP from RbConfig, set LDXX

* enable overriding ranlib command in top-level makefile

* ensure the -no_warning_for_no_symbols flag is only used with Apple's ranlib

* don't embed openssl & zlib on truffleruby

* add RbConfig's cppflag to CPPFLAGS when using TruffleRuby

* this ensure the paths to find the system's OpenSSL are set up correctly with TruffleRuby (includes being able to find an OpenSSL installed via Homebrew etc)

* don't statically link standard libraries on Linux with Truffleruby

* This does not work when compiling to bitcode.

* Prefer SIGTERM to SIGQUIT for graceful shutdown in examples

* Overriding SIGQUIT is suboptimal, for example on JVM where it is very
  useful to dump the thread stacktraces.

* Keep the rb_tr_abi_version symbol for TruffleRuby in grpc_c.so

* Otherwise TruffleRuby cannot verify the ABI version is correct.
* See https://github.com/oracle/truffleruby/issues/2386

* Use RbConfig::CONFIG['STRIP'] instead of just `strip`

* Use a local variable for apple_toolchain for consistency

* Add a comment about -static-libgcc -static-libstdc++ and TruffleRuby

* Split comment into two for openssl/zlib
