Using the latest git top-of-tree, libglib2 fails to compile as follows:-

$ git pull
Already up-to-date.
$ make

configure: error: Package requirements (libffi >= 3.0.0) were not met:

Package libffi was not found in the pkg-config search path.
Perhaps you should add the directory containing `libffi.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libffi' 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 LIBFFI_CFLAGS
and LIBFFI_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Any clues ?

Below is my "defconfig" as created by 'make savedefconfig'.
