tests: use ${CC} instead of 'gcc' in tests
To better support cross-compilation Gentoo provides a way
to configure system without 'gcc' binary and only provide
tool-prefixed tools, like 'x86_64-pc-linux-gnu-gcc'.
The packages are built as ./configure --host=x86_64-pc-linux-gnu.
In https://bugs.gentoo.org/718872 Agostino Sarubbo found
a few test failures that use hardcoded 'gcc' instead of
expected ${CC}. The change propagates detected ${CC} at
configure time to test scripts.

debuginfod: sqlite3 metrics
Add metrics for tracking sqlite3 error counts and query performance.
The former looks like a new sibling of the "error_count" family, and
is tested by dd-corrupting a live database file then triggering some
debuginfod activity.
error_count{sqlite3="file is not a database"} 1
The latter looks like _count/_sum pairs for each type of sqlite
prepared-statement used in the code, and is grep smoke-tested. They
should assist a sysadmin in tuning db storage. This example shows a
