If you have the "profile" USE flag for cogle, then ./configure tries to find "uprof" which doesn't seem to exist in portage:
checking for COGL_DEP... no
configure: error: Package requirements ( cairo >= 1.10 uprof-0.3 gobject-2.0 gmodule-no-export-2.0 gdk-pixbuf-2.0 >= 2.0 x11 xext xfixes >= 3 xdamage xcomposite >= 0.4 xrandr >= 1.2) were not met:
No package 'uprof-0.3' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables COGL_DEP_CFLAGS
and COGL_DEP_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
The ebuild kinda makes mention of this.

Reading configure.ac, looks like it was the same for 1.14.0. Will disable profiling for now until we have uprof in the tree

KEYWORDS should fit the arches you have really tested ;)
Also, I would open a new bug for it (and assign to maintainer-needed, CCing gnome team) as maybe other people would be interested in maintaining it :|
This version of cogl is no longer in portage and the version that is does not have a `profile` USE flag.
