So tried once again with 5.1.

Problem was related to -std=c99 flag:

.obj/release-shared/pcre16_jit_compile.o

I added
QMAKE_CFLAGS+= -std=gnu99 (for using asm function in PCRE)
QMAKE_CXXFLAGS += -std=c++98
 and it now compiles. As an excuse I would like to inform that sysroot I am
working with is VERY inconsistent... forget about adding
/include
/usr/include
/lib
/usr/lib

There are tens of different paths and defines. So I built some examplary
appllication with platform makefile based build system and copied
includepaths, defines and compiler flags from make VERBOSE=1 command to
qmake.conf. It compiled.

In the end however I have encounter:
https://bugreports.qt-project.org/browse/QTBUG-31817#comment-208125

I made some investigation and currently qtjsbackend is broken on mips
architecture. v8 need to be updated(see my comment in mentioned task).
