Warnings during make check

Warnings during make check

[Christer Solskogen]

Hi!

Are these types of warnings OK to ignore or should they be fixed?
Ubuntu 21.04 - gcc version 10.3.0 - binutils 2.36.1 - running "make 
check" on glibc master.

/usr/bin/ld: /tmp/glibc-build/stdlib/test-canon2.o: in function 
`do_prepare':

They all test functionality for which warnings are expected when used
outside of glibc.  I do not think there is a good way to suppress those
warnings.  We want to test the actual installed binaries as far as
possible.

Thanks,
