Subject: [PATCH] trace-cmd: Make the build messages to show only file names

Currently, the typical trace-cmd build messages like "COMPILE <file>" and
"BUILD STATIC LIB <file>" show file's full path, instead of just the file
name, as it used to happen before the full support for out-of-tree builds.
This simple patch makes the build messages to look exactly like in the past
by stripping the directory part of each file path, before printing the
message.
