Subject: [ruby-core:33531] [Backport87-Backport#3824] rbconfig.rb generated by cross-compilation do provide correct path for link process

Issue #3824 has been updated by Luis Lavena.

Category set to lib
Assigned to set to Nobuyoshi Nakada

Hello,

I believe I had pinpoint the root of these issues to the definition of CROSS_COMPILING by my fake.rb (used outside ruby build process).

Inspecting to mkmf.rb, around line 1713:

  $DEFLIBPATH = $extmk ? ["$(topdir)"] : CROSS_COMPILING ? [] : ["$(libdir)"]

DEFLIBPATH is empty if CROSS_COMPILING is detected.

I went ahead and removed that specific check:

  $DEFLIBPATH = $extmk ? ["$(topdir)"] : ["$(libdir)"]

And both ruby bundled extensions compiled successfully and this allow me keep CROSS_COMPILING detection in my fake.rb file.

The following patch correct the issue in ruby_1_8_7 branch, but I'm not aware of any other complication in relation to this.

Thank you.
