[ruby-core:95755] [Ruby master Bug#16331] fails to build with BSD make when any -j option is given (including -j 1)

[meta]

Issue #16331 has been updated by meta@vmeta.jp (Koichiro Iwao).

Subject changed from fails to build with BSD make possibly due to race condition to fails to build with BSD make when any -j option is given (including -j 1)

Now it turned out the build fails even `-j 1` is specified. Any value to `-j` option will fail.
Not giving `-j` option goes fine.

Further information from Yuichiro NAITO:

It sounds Ruby hits the issue described in `make -B`:

The conditions in libruby-static and libruby-shared are different intentionally.

> First:
  It seems that it is not intended to call $(PRE_LIBRARY_UPDATE) in Ruby's Makefile,
  when libruby.so.26 is built.
  Comparing to libruby-static library build,
  Ruby's Makefile should be fixed like `Makefile.in.patch`.

[ruby-core:96404] [Ruby master Bug#16331] fails to build with BSD make when any -j option is given (including -j 1)

[yasu]

Issue #16331 has been updated by yasuhirokimura (Yasuhiro KIMURA).

File buildtest-with-bmake-and-j-option.log added

I executed following shell script on my FreeBSD test environment and got attached log file.

``` shell
#!/bin/sh

LANG=C
(
    echo System Information:
    echo ----------------------------------------------------------------------
    dmesg
    echo ----------------------------------------------------------------------
    echo Package Information:
    echo ----------------------------------------------------------------------
    pkg info -aq
    echo ----------------------------------------------------------------------
    cd /tmp
    for ver in 2.6.5 2.7.0-rc2
    do
        echo Test build of ${ver}:
        tar xfpJ /net/freebsd/ports/distfiles/ruby/ruby-${ver}.tar.xz
        cd ruby-${ver}
        echo Configure:
        echo ----------------------------------------------------------------------
        ./configure
        echo ----------------------------------------------------------------------
        echo Build:
        echo ----------------------------------------------------------------------
        make -j $(sysctl -n kern.smp.cpus)
        echo ----------------------------------------------------------------------
        cd ..
        rm -rf ruby-${ver}
    done
) | 2>&1 tee buildtest-with-bmake-and-j-option.log
```

As you can see, `make -j` works fine with 2.6.5 but fails with 2.7.0-rc2.

Does this log mean the following libraries are stopped by `make` due to the first failure in `cxxanyargs` or in yet another branch?

Reported by FreeBSD Ruby folks. Please keep in mind I didn't find out the root cause.

tar xf ruby-2.6.5.tar.gz
cd ruby-2.6.5
./configure --enable-shared --disable-readline --disable-libedit
make -j 8 # any value will cause build failure
