Subject: Fix build for less common build directories names
X-Git-Tag: v2.8.0-rc0~46^2

Fix build for less common build directories names

scripts/tracetool generates a C preprocessor macro from the name of the
build directory. Any characters which are possible in a directory name
but not allowed in a macro name must be substituted, otherwise builds
will fail.
