 this.)

 You can tell pkg-config to look in your cross-compile root using
 $PKG_CONFIG_PATH, $PKG_CONFIG_LIBDIR, and $PKG_CONFIG_SYSROOT_DIR:
 https://linux.die.net/man/1/pkg-config

 But I'm not even sure how you got to this stage.

 lzma is not enabled by default:
 https://gitweb.torproject.org/tor.git/tree/configure.ac#n1077

 So how did it get enabled with that configure command line?
 Did you edit configure, or change env vars?
