FreeBSD has a libsysinfo package which contains GNU libc's sysinfo port.
Some users reported git 2.50.0 was failing to build when this port is
installed and it happened because configure script detected libsysinfo
but -lsysinfo was not added to LDFLAGS, ending up with following error:
scalar.o common-main.o libgit.a xdiff/lib.a reftable/libreftable.a
libgit.a -lz -pthread
ld: error: undefined symbol: sysinfo
This patch [1] was added to git port adding a user option to
enable/disable libsysinfo dependency and fix LDFLAGS when it's enabled.
I'm not sure about what is best approach for git project in this case.
