package/armadillo: needs gcc >= 8

Browse Source 
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: 597d5d10ec ("package/armadillo: bump to version 15.0.1")
