perf build failure:

util/env.c: In function ‘perf_env__arch’:
cc1: error: function may return address of local variable [-Werror=return-local-addr]
util/env.c:166:17: note: declared here

      |                 ^~~

No one to blame but me, for switching the gcc version used to build perf
to gcc 10.3.0 (from 9.4.0). The problem is fixed in the upstream kernel
with commit ebcb9464a2ae3 ("perf env: Do not return pointers to local
variables"). This patch applies to v5.4.y and earlier kernels.

I'll leave it up to you if you want to apply the fix or not; I'll be
happy to work around the problem in my tests otherwise. Either case,

since this is not a new problem.

Thanks,
