check-tcg calls build-tcg which fails:

  BUILD   TCG tests for x86_64-softmmu
  BUILD   x86_64-softmmu guest-tests with cc
/usr/bin/ld: hello: warning: allocated section `.notes' not in segment
/usr/bin/ld: memory: warning: allocated section `.notes' not in segment
  BUILD   TCG tests for x86_64-linux-user
  BUILD   x86_64-linux-user guest-tests with cc
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: cannot find -lc

make[2]: *** [threadcount] Error 1
make[1]: *** [cross-build-guest-tests] Error 2
make: *** [build-tcg-tests-x86_64-linux-user] Error 2

Apparently this is due to the -static flag:

$ gcc  -Wall -Werror -O0 -g -fno-strict-aliasing -m64
tests/tcg/multiarch/threadcount.c -o threadcount  -static -lpthread
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status

Do we need to install these packages?

glibc-static.i686 : C library static libraries for -static linking.
glibc-static.x86_64 : C library static libraries for -static linking.

Or simply ignore testing?

Thanks,

Phil.
