[OE-core] [PATCH 8/11] oeqa/selftest/gcc: Create selftest case for gcc test suite

[Nathan Rossi]

Create a oeqa selftest test case to execute the gcc test suites and
report the results. The results are populated into the extraresults
variable of the test case which are written to testresults.json for
resulttool to analyse.

An additional subclass is created to separate the execution with qemu
linux-user and qemu system. The GccSelfTestSystemEmulated test case
handles setup of the target image as well as execution with runqemu.
