Prior tob3ba26150d("toolchain/toolchain-external/toolchain-external-custom: be more flexible on gcc version"), the default gcc version selected by Buildroot for custom external toolchain was affected by the BR2_ARCH_NEEDS_GCC_AT_LEAST_xyz definitions. Since BR2_riscv selects BR2_ARCH_NEEDS_GCC_AT_LEAST_7, gcc 7.x was the default gcc version assumed to be used in a custom RISC-V external toolchain, so our config snippets for RISC-V toolchains were correct. Withb3ba26150dapplied, the default gcc version assumed for custom external toolchains is the latest one (currently gcc 9.x), while our RISC-V toolchains use gcc 7.x. So we now need to explicitly give the gcc version used by our RISC-V toolchains, otherwise the build fails with: Incorrect selection of gcc version: expected 9.x, got 7.4.0 Fixes: http://autobuild.buildroot.net/results/b872befe1adec2633b9cbcc49bc0eb7619f606c2/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
