[bug#49019] [PATCH 0/1] gnu: Add gccgo-10.

[Sarah Morgensen]

The primary goal for adding gccgo is to bootstrap the go compiler for arches
that aren't supported by go 1.4. I believe the major one to support here is
powerpc64le, but I am unsure of current arch usage. A secondary goal is to
provide a gccgo-toolchain, as gccgo may provide advantages over gc in time.

I have successfully built gccgo 9, 10 and 11 for x86-64. I additionally tested
gcc 10 using `make check-go`. There are two minor test failures:

1. index0-out.go, previously reported upstream [0]
2. pprof (TestConvertCPUProfile/TestConvertMemProfile)

(I have not yet been able to deterine whether the pprof failures are an upstream
bug or a Guix bug. Should I send details to bug-guix?)

Finally, the regex update in [1] is implemented in CUSTOM-GCC-GCCGO rather than
CUSTOM-GCC to avoid rebuilding 2k+ gfortran packages, and CUSTOM-GCC-GCCGO
should be removed after the change is in master.
