The -lm linker option is not known to MSVC and setting it triggers
errors in some build systems:
[6,366 / 6,367] Linking source/exe/envoy-static.exe; 11s remote
LINK : warning LNK4044: unrecognized option '/lm'; ignored
LINK : error LNK1218: warning treated as error; no output file generated
ERROR: C:/source/source/exe/BUILD:22:16: Linking of rule
'//source/exe:envoy-static' failed (Exit 4044): link.exe failed: error
executing command
Do not set -lm in case of MSVC.
