Subject: build-many-glibcs: relax version check to allow non-digit characters
X-Git-Tag: glibc-2.40~435
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0d70accc06a9cbb9b13004116f5fa8b1f41a7150;p=thirdparty%2Fglibc.git

build-many-glibcs: relax version check to allow non-digit characters

A version string may contain non-digit characters, commonly found in
built-from-VCS tools, e.g.
```
git version 2.39.GIT
git version 2.43.0.493.gbc7ee2e5e1
```

`int()` will raise a ValueError, leading to a spurious 'missing'.
