Ruby

I just updated Ruby from 3.1.2 to 3.1.3 and found out that all .so libraries from the enc directory have wrong RPATH/RUNPATH (when building with --enable-rpath). I first hit this on Solaris, but my testing on Linux resulted in the same thing. It can be easily reproduced with the following:

wget http://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.3.tar.gz tar xzf ruby-3.1.3.tar.gz cd ruby-3.1.3 ./configure --prefix=/usr/ruby/3.1 --mandir=/usr/ruby/3.1/share/man --bindir=/usr/ruby/3.1/bin --sbindir=/usr/ruby/3.1/sbin --libdir=/usr/ruby/3.1/lib/amd64 --with-rubylibprefix=/usr/ruby/3.1/lib/ruby --enable-shared --enable-rpath /usr/bin/make -j 16 -l 32 objdump -x ./.ext/x86_64-linux/enc/windows_31j.so | grep RPATH 

While previously this resulted in the following output:
RPATH /usr/ruby/3.1/lib/amd64

in 3.1.3 it is wrongly set to the build directory:
RPATH /home/jkulik/rubytest/ruby-3.1.3

I tried looking for some obvious change but didn't find the core of this issue yet. All I found out is that generated enc.mk differs in prefix and libdir

-prefix = /usr/ruby/3.1 +prefix = /home/jkulik/rubytest/ruby-3.1.3 exec_prefix = $(prefix) -libdir = $(exec_prefix)/lib/amd64 +libdir = /home/jkulik/rubytest/ruby-3.1.3 

rbconfig.rb is similar in both versions, but when I print out CONFIG in make_encmake.rb right after load File.expand_path("lib/mkmf.rb", dir), I can see the differences from above, so it's probably something in the lib/mkmf.rb file that changes that.

I am seeing the same issue in the current latest ruby 3.1 branch cloned from github.
