Recent GCC versions seem to be more picky on the ordering of object
files and libraries on the linking command line. Check the printed gcc
command lines to see if -lpthread is towards the end of the line. To
fix this you will need to find the makefile (I assume the build
process is using make?) where the linking command is built up, e.g.
"$(LD) something". The list of libraries might be contained in a LIBS
or LDFLAGS variable.

If you pastebin the build log it would be easy to see if this could be
the issue. Especially the command line generating the error message
would be useful.

The gcc version might be important. The kernel you are running does
not matter, only the kernel headers would matter if you were building
kernel modules. I am just saying that for clarification, if in doubt,
rather provide more information than less.
