[OE-core] [PATCH 1/2] perf: mkdir ${B} -> mkdir -p ${B}

[Robert Yang]

${B} is the default cwd of tasks, so there might be race issues such as:
| mkdir: cannot create directory `/path/to/work/qemux86-poky-linux/perf/1.0-r9/perf-1.0/': File exists
[snip]
NOTE: recipe perf-1.0-r9: task do_configure: Failed
