## Description:

This update for go1.24, go1.23, go1.22, go1.21 fixes the following issues:

Changes in go1.24:

  * Use libalternatives only on suse_version >= 1610 and keep update-
    alternatives support for older distributions.
  * Drop the update-alternatives migration path for libalternatives builds.

  * Packaging: Enable libalternatives for SLE16.1 and Tumbleweed Refs
    boo#1245878

  * Drop go1.24 dependency on update-alternatives fixes bsc#1264393

Changes in go1.23:

  * Use libalternatives only on suse_version >= 1610 and keep update-
    alternatives support for older distributions.
  * Drop the update-alternatives migration path for libalternatives builds.

  * Packaging: Enable libalternatives for SLE16.1 and Tumbleweed Refs
    boo#1245878

  * Drop go1.23 dependency on update-alternatives fixes bsc#1264392

  * Packaging improvements:

  * Remove conditional gccgo bootstrap sections and gcc-go patch. gccgo cannot
    be used in any version newer than go1.21. Removal simplifies go1.x package
    code.
  * go1.21 can optionally be bootstrapped with gccgo and serve as the inital
    version of go1.x.
  * go1.21 will be the initial version of Go in the bootstrap chain until gcc
    gccgo is updated to support a language level newer than go1.18.
  * Refs boo#1247816 bootstrap go1.21 with gccgo
  * Refs boo#1248082 drop unused gccgo bootstrap code in go1.22+

Changes in go1.22:

  * Use libalternatives only on suse_version >= 1610 and keep update-
    alternatives support for older distributions.
  * Drop the update-alternatives migration path for libalternatives builds.

  * Packaging: Enable libalternatives for SLE16.1 and Tumbleweed ( boo#1245878)

  * Drop go1.22 dependency on update-alternatives fixes bsc#1264391

  * Packaging improvements:

  * Remove conditional gccgo bootstrap sections and gcc-go patch. gccgo cannot
    be used in any version newer than go1.21. Removal simplifies go1.x package
    code.
  * go1.21 can optionally be bootstrapped with gccgo and serve as the inital
    version of go1.x.
  * go1.21 will be the initial version of Go in the bootstrap chain until gcc
    gccgo is updated to support a language level newer than go1.18.
  * Refs boo#1247816 bootstrap go1.21 with gccgo
  * Refs boo#1248082 drop unused gccgo bootstrap code in go1.22+

Changes in go1.21:

  * Use libalternatives only on suse_version >= 1610 and keep update-
    alternatives support for older distributions.
  * Drop the update-alternatives migration path for libalternatives builds.

  * Packaging: Enable libalternatives for SLE16.1 and Tumbleweed Refs
    boo#1245878

  * Drop go1.21 dependency on update-alternatives fixes bsc#1264390

  * Prepare for removing old go versions from Factory:

  * Switch default for go1.21 to bootstrap with gcc-go using %bcond_without
    gccgo_go121
  * Building go1.21 with gcc-go by default removes need for prjconf
  * Refs boo#1247816 bootstrap go1.21 with gccgo
