I would prefer increasing the timeout to disabling the test.

The blackbox tests start qbs in a subprocess and wait for it to finish in a
reasonable time [1]. The value of testTimeoutInMsecs() can be configured by
QBS_AUTOTEST_TIMEOUT environment variable, which specifies time in seconds and
is 600 by default, which is 10 minutes.

However, Qt test library has its own timeout: any test function call is
interrupted in 5 minutes [2]. This can be configured by QTEST_FUNCTION_TIMEOUT
variable, which is in milliseconds. It looks like this is the timeout that
occurs in the log fragments you provided.

Do you have any way to check if increasing QTEST_FUNCTION_TIMEOUT helps to
get it built on slow riscv64 machines. And if yes, to what value it should
be increased?
