Subject: [PATCH AUTOSEL 6.6 08/31] selftests/sgx: Fix linker script asserts

From: Jo Van Bulck <jo.vanbulck@...kuleuven.be>

[ Upstream commit 9fd552ee32c6c1e27c125016b87d295bea6faea7 ]

DEFINED only considers symbols, not section names. Hence, replace the
check for .got.plt with the _GLOBAL_OFFSET_TABLE_ symbol and remove other
(non-essential) asserts.
