This appears to work nicely. After running autoreconf and ./configure
--disable-libssh it builds a bird with RPKI support, which is still "lean":
DEV 2.x MIPS:~/bird-patch> ldd bird
linux-vdso.so.1 (0x771ed000)
libpthread.so.0 => /lib/mips-linux-gnu/libpthread.so.0 (0x770a2000)
libc.so.6 => /lib/mips-linux-gnu/libc.so.6 (0x76f20000)
/lib/ld.so.1 => /lib64/ld.so.1 (0x771bc000)
however, attempts to build it without --disable-libssh result in a linking
error:
/tmp/ccz8W8kL.ltrans12.ltrans.o: In function `rpki_init_cache':
/home/csch/bird-patch/proto/rpki/rpki.c:583: undefined reference to

/home/csch/bird-patch/proto/rpki/rpki.c:583: undefined reference to
`rpki_tr_ssh_init'
collect2: error: ld returned 1 exit status
It still works without the patch, but (as mentioned) yields a bird with many
external dependencies:

To summarize → your patch works fine in "the forward direction" (towards
solving the problem), but apparently creates another problem when building with
libssh now.
🤷🏼♂️
Thanks for your efforts!
