Subject: [PATCH core-updates] gnu: bootstrap-gcc: Don't use CPATH search paths.
Date: Sun,  2 Aug 2020 22:34:21 +0200

This updates the bootstrap-gcc to use the same search path strategy as
the main compilers, making the bootstrap environment more similar across
architectures, and fixing the bootstrap path on non-x86 architectures
again.

This is a follow up to commit 7cde865f12dd67e55946a52a21103e71f447eced.

* gnu/packages/bootstrap.scm (%bootstrap-gcc)[native-search-paths]: Use
  C_INCLUDE_PATH and CPLUS_INCLUDE_PATH instead of CPATH.
---

Note: because I don't have any non-x86 machines on hand, I haven't
actually tested the patch yet.

Efraim, you have helped me investigate this with your ARM board, perhaps
you could test this patch?

Regards,
Jakub Kądziołka
