gnu: Switch to GCC 11.
* gnu/packages/commencement.scm (gcc-boot0)[source]: Delete offending files
from GCC.
(libstdc++-boot0)[arguments]: Add #:modules.
(libstdc++): Inherit from from GCC-BOOT0 rather than GCC.
(gcc-final)[arguments]: Add phase to workaround libstdc++ build system issue.
Add #:modules.
* gnu/packages/gcc.scm (make-libstdc++): Likewise.
