Thomas Petazzoni 77fc458025 Revert "toolchain/toolchain-external: error if BR2_TOOLCHAIN_EXTERNAL_PATH is not set"
This reverts commit 8e91385a2c.

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.

Commit 392b0a26f5 ("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
8945ba4948 (the backport of 8e91385a2c to
the 2022.02.x LTS branch) breaks his use-case:

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.
