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: 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: reference 8e91385a2c on master] Signed-off-by: Yann E.
