The documentation currently specifies SGX_SIGNER_KEY as the parameter to
enable Graphene to find your keys.
Some examples don't use this environment parameter, this commit fixes
that.
On Ubuntu 'which' finds 'cp' in '/bin/cp' and on Fedora in
'/usr/bin/cp'. Rather than hard-coding the path '/bin', use
$(EXECDIR) and derive its value from the dirname of the path of the
executable, i.e., either '/bin' or '/usr/bin'.
Extend Makefile.configs and define several variables for make to use
derived from 'gcc -dumpmachine'. In particular:
- ARCH as the architecture, e.g., x86_64
- ARCH_LONG as the long version of the architecture, e.g., x86_64-linux-gnu
- ARCH_LIBDIR as the directory where libraries are located,
e.g., /lib/x86_64-linux-gnu
In Makefiles and manifest templates, replace the hard-coded
x86_64-linux_gnu and /lib/x86_64-linux-gnu through these variables.
Extend the already existing sed scripts to replace the necessary
variables.
