[PATCH] trace-cmd: Update make-trace-cmd.sh to handle pkg-config without --with-path

[PATCH] trace-cmd: Update make-trace-cmd.sh to handle pkg-config without --with-path

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Debian and Ubuntu's pkg-config does not support the "--with-path" option.
Check first if it is supported, and only use it when it is.

Set PKG_CONFIG_PATH to inform pkg-config where to search.

Note, this script may not be the best way to create packaging and there may
be better ways to do so.
