[PATCH v2 07/11] tests/tcg: relax the next step precision of the gdb sha

From: Alex Bennée
Subject: [PATCH v2 07/11] tests/tcg: relax the next step precision of the gdb sha1 test
Date: Thu, 1 Apr 2021 11:25:26 +0100

Depending on the version of gdb we may not execute the first line of
SHA1Init when executing the first "next" command - instead just
stepping over the preamble. As we don't actually care about the
position of the PC after the steps and want to be sure the
context->state[] has been loaded before we inspect it do a double next
at the start.
