pkg/csource: build executor w/o optimizations
Build executor w/o optimizations for tests.
Tests can build lots of versions of executor in parallel,
and on overloaded machines it can be slow. On my machine
this reduces executor build time from ~7.5 to ~3.5 secs.
Reduces pkg/runtest tests time considerably.
Before:
--- PASS: TestExecutor (8.89s)
--- SKIP: TestExecutor/386 (0.00s)
--- PASS: TestExecutor/riscv64 (30.76s)
--- PASS: TestExecutor/arm (32.56s)
--- PASS: TestExecutor/arm64 (33.01s)
--- PASS: TestExecutor/amd64 (31.83s)
--- SKIP: TestExecutor/ppc64le (26.56s)
--- PASS: TestExecutor/s390x (25.53s)
--- PASS: TestExecutor/mips64le (25.65s)
After:
--- PASS: TestExecutor (4.74s)
--- SKIP: TestExecutor/386 (0.00s)
--- PASS: TestExecutor/s390x (12.27s)
