Simple 'scons -c' is not enough.  When I do that I duplicate your
earlier error:

/usr/lib/gcc/x86_64-pc-linux-gnu/6.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: 
./libgpsd.a(ppsthread.o): undefined reference to symbol 
'pthread_create@@GLIBC_2.2.5'
/lib64/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

Here is the script I use that always works:

    git clone https://git.savannah.nongnu.org/git/gpsd.git
    cd gpsd
    scons --clean
    scons distclean
    scons sconsclean
    scons --config=force && scons install

Looks like your issue is the configuration part does not work well by
default, and what does work is not preoprtly documented.
