[Buildroot] [git commit branch/2018.05.x] pixiewps: fix static linking with uclibc-ng

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=1a6e14b4be0d1950a22a2bc73edb5759361858c0
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.05.x

Fixes following linking error with uClibc-ng:
/home/peko/autobuild/instance-0/output/host/lib/gcc/powerpc-buildroot-linux-uclibc/7.3.0/libgcc.a(unwind-dw2-fde-dip.o):
In function `_Unwind_Find_FDE':
/home/peko/autobuild/instance-0/output/build/host-gcc-final-7.3.0/build/powerpc-buildroot-linux-uclibc/libgcc/../../../libgcc/unwind-dw2-fde-dip.c:469:
undefined reference to `dl_iterate_phdr'
collect2: error: ld returned 1 exit status

Since uClibc-ng 1.0.18 a circular dependency between libc and libgcc
exist, when static linking is used. It can be resolved by the compiler
when -static is correctly passed in the linking step.

So use TARGET_CONFIGURE_OPTS to pass CC as well as LDFLAGS to make
