Subject: [PATCH] build: Avoid warnings about unknown pragmas.

In commit 4bbbf03b8bc266ed2b63c461cd0945250bb134fe we started to

ignore bogus GCC 11 warnings.  Unfortunately earlier versions of GCC

don't know about those pragmas so give warnings [hence errors in

developer builds] like:

tsk.c:75:32: error: unknown option after '#pragma GCC diagnostic' kind [-Werror=pragmas]

Turn off these warnings.

Updates: commit 4bbbf03b8bc266ed2b63c461cd0945250bb134fe

(cherry picked from commit 812f837c97f48ce0c26a0e02286fb9180c282923)
