bpftrace failing to migrate due to autopkgtest failure https://objectstorage.prodstack5.canonical.com/swift/v1/AUTH_0f9aae918d5b4744bf7b827671c86842/autopkgtest-oracular/oracular/amd64/b/bpftrace/20240716_075041_862af@/log.gz

The basic.defines test is failing.

The following command is valid in bash.

RUN {{BPFTRACE}} -e "$(echo '#define _UNDERSCORE 314'; echo 'BEGIN { printf("%d\n", _UNDERSCORE); exit(); }')"

But in the test runner dash will be used, which cannot parse the above correctly. Instead I came up with the below replacement that parses in dash producing an equivalent result.

RUN {{BPFTRACE}} -e "$(printf '#define _UNDERSCORE 314\n'; printf 'BEGIN { printf("%%d\\n", _UNDERSCORE); exit(); }')"
