Merge bitcoin/bitcoin#27153: guix: pass --enable-initfini-array to release GCC

127c637 guix: pass --enable-initfini-array to release GCC (fanquake)

Pull request description:

  This returns us to pre-Guix behaviour, where the compilers we were using to build releases, were configured with this option.

  > [--enable-initfini-array](https://gcc.gnu.org/install/configure.html)
  > Force the use of sections .init_array and .fini_array (instead of .init and .fini) for constructors and destructors. Option --disable-initfini-array has the opposite effect. If neither option is specified, the configure script will try to guess whether the .init_array and .fini_array sections are supported and, if they are, use them.
