Due to report on OVS failing to build I happened to find that 19.11.4
has massively changed linking.
=> https://paste.ubuntu.com/p/znCRR4gpjP/

This was meant to be helpful for sure and I assume is around:
48f7fd27f6 build/pkg-config: prevent overlinking
2d1535d592 build/pkg-config: improve static linking flags
9fb13a12c1 build/pkg-config: output drivers first for static build
59b108d824 build/pkg-config: move pkg-config file creation
aea915e944 devtools: test static linkage with pkg-config

But overlinking has effectively become underlinking now
https://launchpadlibrarian.net/495845224/buildlog_ubuntu-groovy-amd64.openvswitch_2.13.1-0ubuntu2~ppa1_BUILDING.txt.gz

/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/librte_pmd_ring.a(net_ring_rte_eth_ring.c.o):
in function `rte_eth_from_rings':
(.text+0x91c): undefined reference to `rte_vdev_init'
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/librte_pmd_ring.a(net_ring_rte_eth_ring.c.o):
in function `vdrvinitfn_pmd_ring_drv':
(.text.startup+0x28): undefined reference to `rte_vdev_register'
collect2: error: ld returned 1 exit status

Also as you can see in the pastebin above, CFlags and Libs massively
shrunk and likely too much so.

Given that this should be a stable release I'd ask to back out those
changes so that a test build creates the same .pc file as before -
would that make sense?
