[Buildroot] [PATCH] dbus: use -pthread instead of -lpthread

[Vicente Olivert Riera]

This fixes a problem in other packages when they link against dbus. For
instance, with the dnsmasq package:

/buildroot/output/host/usr/bin/mipsel-ctng-linux-uclibc-gcc --static
-lidn  -o dnsmasq cache.o rfc1035.o util.o option.o forward.o network.o
dnsmasq.o dhcp.o lease.o rfc2131.o netlink.o dbus.o bpf.o helper.o
tftp.o log.o conntrack.o dhcp6.o rfc3315.o dhcp-common.o outpacket.o
radv.o slaac.o auth.o ipset.o domain.o dnssec.o blockdata.o
-L/buildroot/output/host/usr/mipsel-buildroot-linux-uclibc/sysroot/usr/lib
-ldbus-1 -lpthread
-L/buildroot/output/host/usr/mipsel-buildroot-linux-uclibc/sysroot/usr/lib
-lidn -liconv
-L/buildroot/output/host/usr/mipsel-buildroot-linux-uclibc/sysroot/usr/lib
-llua -lm     -Wl,-Bstatic -lhogweed
-L/buildroot/output/host/usr/mipsel-buildroot-linux-uclibc/sysroot/usr/lib
-lnettle -lgmp   -Wl,-Bdynamic -Wl,-Bstatic -lgmp -Wl,-Bdynamic
/buildroot/output/host/usr/mipsel-buildroot-linux-uclibc/sysroot/usr/lib/libpthread.a(init.os):
In function `__pthread_initialize_minimal_internal':
init.c:(.text+0x26c): undefined reference to `__libc_setup_tls'
collect2: error: ld returned 1 exit status
