	Use libSystem.dylib instead of libm.dylib and libc.dylib

	  Because macOS 11.0(Big Sur) was removed libc and libm from `/usr/lib`.

	libSystem.dylib is also symlink. Use libSystem.B.dylib

	Workaroud for macOS Big Sur(11.0)

Fix "cannot find the function: strcpy()" error on arm32 on Travis CI. (#2686)

2019-12-05T05:17:16+00:00

This issue happened when `libc.so` and `libm.so` path were not found
and `ldd ruby` command also failed to print the shared dependencies
in `test/fiddle/helper.rb`.

See https://travis-ci.org/ruby/ruby/jobs/611483288#L3018
/home/travis/build/ruby/ruby/build/.ext/common/fiddle/import.rb:299:in `import_function': cannot find the function: strcpy() (Fiddle::DLError)

* Set libc6:armhf as a installing dependency explicitly.
* Remove arm32 from allow_failures.

Deprecate taint/trust and related methods, and make the methods no-ops

2019-11-17T23:00:25+00:00

This removes the related tests, and puts the related specs behind
version guards.  This affects all code in lib, including some
libraries that may want to support older versions of Ruby.

[ruby/fiddle] Remove taint support (#21)

2019-10-24T10:34:49+00:00

Ruby 2.7 deprecates taint and it no longer has an effect.
The lack of taint support should not cause a problem in
previous Ruby versions.
