Does tst_net_ip_prefix really wants two glibc versions?

Agree, please run configure just as:
./configure CROSS_COMPILE="/build/fpsdkroot_cougar/sysroots/mips/sysroot-wrlinux-4.3-NSN6607-fp_octwnd_6880_ampp2-glibc_cgl/x86-linux2/mips-wrs-linux-gnu-mips64_octeon2-glibc_cgl-" --host=mips-wrs-linux-gnu

BTW you can see that cross LTP compilation works on travis (tested on arm):
https://travis-ci.org/linux-test-project/ltp/branches
https://travis-ci.org/linux-test-project/ltp/jobs/329049819
https://travis-ci.org/linux-test-project/ltp/jobs/329049820
It's tested on arm, but it should be the same for mips. It uses ./build.sh script, which
you can use locally as well.


Kind regards,
Petr
