The external tests manipulating page permissions expect encl_buffer to be placed at the start of the test enclave's .data section. As this is not guaranteed per the C standard, explicitly place encl_buffer in a separate section that is explicitly placed at the start of the .data segment in the linker script to avoid the compiler placing it somewhere else in .data.
