IANAL either.

Some further clarification.  See COPYING.NEWLIB and COPYING.LIBGLOSS for
target-specific licensing for
a newlib/libgloss library built from current sources.

The fr30 is no longer GPL and this is stated in COPYING.NEWLIB.  The linux
target is no longer in the newlib sources and as Brian noted, was LGPL.

For libgloss, the sparc-*leon*, crx-*, cr16-* targets have a GPL with
exception license.  The exception states
that code linked with the libraries built from said sources have no
restrictions.  See the rest of the license
for full explanation of other usages.

The top-level directory files are shared with other gnu projects such as
binutils and gcc.  Configuration and build files
used from there do not affect the licensing of the newlib/libgloss
libraries that are built.
