commit: https://gitlab.com/buildroot.org/buildroot/-/commit/67b026da25c1b87709b0eea8d94d8ee2ca51cd06
branch: https://gitlab.com/buildroot.org/buildroot/-/tree/2026.05.x
Upstream bumped the minimum required gcc version from 6.1 to 8.1 in
commit 84ec3ddf9fd3 ("bump minimum gcc version to 8.1"), so the build
now fails with "Compiler too old; need at least gcc 8.1" on older
toolchains.
There is no gcc 8.0.x release (the 8.x series starts at 8.1.0), so
BR2_TOOLCHAIN_GCC_AT_LEAST_8 is enough to express this dependency.
While at it, add the gcc version to the openblas-arch comment, which
only checked for C++ support and would therefore stay hidden on
toolchains that are too old.
Fixes: 597d5d10ec77 ("package/armadillo: bump to version 15.0.1")
