Subject: toolchain: drop $(REVISION) from GCC version
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9292f32fd96dc00b7c3f34a028d1fc41a4fcb6d2;p=thirdparty%2Fopenwrt.git

toolchain: drop $(REVISION) from GCC version

Storing the ever changing revision in the GCC binary may result in leakage in
package builds. If two equal GCC versions build the same package version with
different OpenWrt revisions, the package becomes unreproducible.

Solve this by dropping the revision.

Below is an example of the `cni` package:

    │ ├── readelf --wide --decompress --string-dump=.comment {}
    │ │ @@ -1,4 +1,4 @@
    │ │
    │ │  String dump of section '.comment':
    │ │ -  [     0]  GCC: (OpenWrt GCC 14.4.0 r35470-1b2aeb4f8a) 14.4.0
    │ │ +  [     0]  GCC: (OpenWrt GCC 14.4.0 r35485-0f256a0a7a) 14.4.0
