I’m not running using make -j1 but I tried it anyway and several other
parameter (e.g. -j20) but it did not resolve the issue.
Sorry for the confusion regarding I/use/include. Must be because I added
KERNEL_HEADERS=/usr/include to my make command for the sake of trying
various solution to solve the issue (but it did not help at all). I have
checked my scripts and made sure there are no additional CFLAGS or anything
of that sort included. I even tried to run the commands outside my bash
scripts in normal terminal and still the error popped up. One dirty
solution is to copy libc.a and libpthread.a from /tools/lib to /lib and it
solves the problem but it is not an elegant solution. Do you think there is
a way to skip those tests that rely on static libraries in libcap to avoid
this problem?
