Commit 78724357 added versions 2019.5 to 2019.8 but failed to update
the patches for these versions.
1. gcc_generic-pedantic patch -- include this up through 2019.5. This
was fixed in the TBB source tree in 2019.6.
2. tbb_cmakeConfig patch -- this needs to be modified (different file)
for 2019.5 and later.
3. tbb_gcc_rtm_key patch -- replace this with filter_file. This is
simpler and eliminates the need to update the patch whenever the
surrounding context changes.
