Subject: pkg-cmake.mk: refactor the toolchainfile.cmake generation
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=85fea5d9538e8ea1d1f83c7aa517ffebff7a4f1f;p=buildroot.git

pkg-cmake.mk: refactor the toolchainfile.cmake generation

This patch introduces a toolchainfile.cmake.in template which is filled
by Buildroot.

Using a toolchainfile.cmake.in template file allows to avoid overloading
quoting and/or escaping and it becomes much more similar to the
resulting file.

This patch also cleans up the quoting style.

[Peter: drop stdin redirect as suggested by Thomas]
