2. guix: fix GCC 10.3.0 + mingw-w64 setjmp/longjmp issues

   This commit backports a patch to the GCC 10.3.0 we build for Windows
   cross-compilation in Guix. The commit has been backported to the GCC
   releases/gcc-10 branch, but hasn't yet made it into a release.
   
   The patch corrects a regression from an earlier GCC commit, see:
   https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=357c4350680bf29f0c7a115424e3da11c53b5582
   and
   https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=074226d5aa86cd3de517014acfe34c7f69a2ccc7,
   related to the way newer versions of mingw-w64 implement setjmp/longjmp.
   
   Ultimately this was causing a crash for us when Windows users were
   viewing the network traffic tab inside the GUI. After some period, long
   enough that a buffer would need reallocating, a call into FreeTypes
   gray_record_cell() would result in a call to ft_longjmp (longjmp), which
   would then trigger a crash.
   
   Fixes: https://github.com/bitcoin-core/gui/issues/582.
