Linker errors building Qt from source on Linux

I am trying to build Qt from source on Linux.
System is Ubuntu 16.04 with GCC 5.4.

I have experienced the same issue with 5.9.6 and 5.11.2.

I am configuring it this way:

./configure -c++std c++14 -qt-pcre -qt-zlib -qt-libjpeg -qt-libpng -qt-harfbuzz -qt-freetype -skip qtwebengine -no-avx512

And then just simply

make -j8 install

Early in the build, I get the following failure:

/usr/bin/ld.gold: error: cannot find -lqtpcre2
.obj/qregularexpression.o:qregularexpression.cpp:function safe_pcre2_match_16(pcre2_real_code_16 const*, unsigned short const*, int, int, int, pcre2_real_match_data_16*, pcre2_real_match_context_16*): error: undefined reference to 'pcre2_match_16'
.obj/qregularexpression.o:qregularexpression.cpp:function safe_pcre2_match_16(pcre2_real_code_16 const*, unsigned short const*, int, int, int, pcre2_real_match_data_16*, pcre2_real_match_context_16*): error: undefined reference to 'pcre2_jit_stack_create_16'

(Followed by a lot more missing symbols from pcre2).

If I invoke make again, the build proceeds fine. 

It also works fine if after the error I go to the following directory:

./qt-everywhere-src-5.11.2/qtbase/src/3rdparty/pcre2

And invoke make there, and then invoke make from the top level directory. At that point, it failed again due to a similar issue with harfbuzz, for which I followed the same workaround.

So, libpcre2.a is compiling just fine, but for some reason during the main build it is required before it was built.

There have been times where I have got it to build without any errors, under the same conditions, so it doesn't appear to be 100% reproducible. However, most times I've tried, my build fails.

Is it possible that the compile time dependencies are not being built in the right order?
