[Bug 51051] wine-staging 6.7 64 bit build fails in Ubuntu 21.04

[WineHQ Bugzilla]

--- Comment #3 from Zebediah Figura  ---
Sorry, but I incorrectly read the log. The LTO thing is a warning, not fatal.
What is fatal is this:

[  314s] /usr/bin/ld: /tmp/wine64-preloader.OWmPvo.ltrans0.ltrans.o: in
function `_start':
[  314s] <artificial>:(.text+0x12): undefined reference to `thread_data'
[  314s] /usr/bin/ld: <artificial>:(.text+0x2a): undefined reference to
`wld_start'

Unfortunately I still have no idea why wine-staging would affect this; we don't
have any patches that touch the loader.
