This reverts commit8e91385a2c. This commit is incorrect, as it is perfectly valid for BR2_TOOLCHAIN_EXTERNAL_PATH to be empty. The help text of BR2_TOOLCHAIN_EXTERNAL_PATH even documents it as a supported case: If empty, the compiler will be searched in $PATH. Commit392b0a26f5("toolchain-external: default BR2_TOOLCHAIN_EXTERNAL_PATH to empty") even made that the default saying "In addition, it in fact works correctly when it is empty. In that case, the toolchain will be searched in PATH." A user has reported that commit 8945ba49480a7885d104445ca855ef7681a374ff (the backport of8e91385a2cto the 2022.02.x LTS branch) breaks his use-case: https://lore.kernel.org/buildroot/CADBnMvhgaozAgZgy3njckjL1i0U6bZ0fLrq-kdFF-qpGhFWgmw@mail.gmail.com/ Reported-by: Kristof Havasi <havasiefr@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> [yann.morin.1998@free.fr: reference8e91385a2con master] Signed-off-by: Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
