test_proc_cmdline_get_bool fails with -Defi=false

[floppym]

systemd version the issue has been seen with
v244-rc1

Used distribution
Gentoo

Description
When I build systemd targeting the i686 ABI on an x86-64 system, I get the test failure below. This may be triggered by some option passed to meson; I suspect something to do with the EFI options.

336/509 test-proc-cmdline                       FAIL     0.64 s (killed by signal 6 SIGABRT)

This appears to be triggered by passing -Defi=false to meson.
