If a CPUTYPE isn't specified, then don't use -march=k8 when compiling
32-bit compat libs on amd64 since -march=k8 may generate instructions that are not implemented on Intel EM64T processors. Instead, use a simpler set of default flags that should work on all amd64-capable CPUs. PR: amd64/113111 Submitted by: NIIMI Satoshi sa2c of sa2c.net MFC after: 1 week
