configure.ac: fix static build with hwloc
Retrieve hwloc dependencies through pkg-config to avoid the following static build failure: checking for hwloc_get_proc_cpubind in -lhwloc... no configure: error: can not find required library libhwloc This build failure is raised because without pkg-config, hwloc dependencies such as libxml2 are not retrieved: configure:8999: checking for hwloc_get_proc_cpubind in -lhwloc configure:9022: /home/autobuild/autobuild/instance-0/output-1/host/bin/powerpc-buildroot-linux-uclibc-gcc -o conftest -D_GNU_SOURCE -I/home/autobuild/autobuild/instance-0/output-1/host/powerpc-buildroot-linux-uclibc/sysroot/usr/bin/../../usr/include -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Og -g0 -static -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -static conftest.c -lhwloc -llzma -L/home/autobuild/autobuild/instance-0/output-1/host/powerpc-buildroot-linux-uclibc/sysroot/usr/bin/../../usr/lib -lncurses -lm >&5 /home/autobuild/autobuild/instance-0/output-1/host/lib/gcc/powerpc-buildroot-linux-uclibc/10.3.0/../../../../powerpc-buildroot-linux-uclibc/bin/ld: /home/autobuild/autobuild/instance-0/output-1/host/powerpc-buildroot-linux-uclibc/sysroot/usr/bin/../../usr/lib/libhwloc.a(topology-xml-libxml.o): in function `hwloc_libxml_free_buffer': topology-xml-libxml.c:(.text+0x6a): undefined reference to `xmlFree' Fixes: - http://autobuild.buildroot.org/results/5d815ec08c580005a863df6ac9ac29deff7d4128 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com>
