The compiler detection since openblas 0.3.8 added support for gcc 10, but
this broke detection of compilers created with crosstool-ng, or other
toolchains that have a package version containing a version like x.y.z where
at least one of x, y or z have more than one digit, for example
"Crosstool-NG 1.24.0".
See the reported issue for more details [1].
Backport the upstream patch that fixes it.
