guix: pass `--enable-initfini-array` to release GCC

fanquake commented at 10:00 am on February 24, 2023: member

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

–enable-initfini-array 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.

I can confirm that this adds relevant .fini_arraysections and gets rid of the .ctors and .dtors sections in the bitcoin x86 _64 linux binaries by comparing the binaries of this PR’s HEAD and its HEAD~1.

EDIT: I am also seeing around ~0.1kb binary size reduction :P
