QProcess does not work properly in Docker on a M1 mac

    Description

      QProcess does not seem to work properly when running inside Docker on a M1 mac, but works great on Intel based macs. When enabling debug messages from qprocess_unix.cpp there is this output when running attached application with ./output /bin/ls:

      QProcessPrivate::startProcess()
QProcessPrivate::waitForStarted(-1) waiting for child to start (fd = 15)
QProcessPrivate::processStarted() == true
QProcessPrivate::waitForStarted() == true
PWC main: returned from waitForStarted
QProcessPrivate::waitForReadyRead(5000)
QProcessPrivate::bytesAvailableInChannel(1) == 0
QProcessPrivate::readFromChannel(1, 0x4000220648 "...", 1) == 0
QProcessPrivate::bytesAvailableInChannel(2) == 0
QProcessPrivate::readFromChannel(2, 0x40002217d8 "...", 1) == 0
QProcessPrivate::waitForDeadChild() dead with exitCode 64 , crashed? true
QProcessPrivate::killProcess()'

      Exit code 64 probably means EX_USAGE. But directly calling execv() with same arguments seems to work.
