--r maintainer,

jack-tools fails to build with ld-as-needed.

The entire buildlog can be found here:

Snippet:
/bin/bash ./libtool --tag=CC   --mode=link gcc -D_POSIX_C_SOURCE=200112 -std=c99 -O3 -funroll-loops -Wall  -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall  -Wl,-Bsymbolic-functions -Wl,-z,relro -ldl -lm -o jack.udp jack_udp-jack.udp.o common/libcommon.a -ljack -lpthread -lrt

/usr/bin/ld: common/libcommon.a(libcommon_a-time-timeval.o): undefined reference to symbol 'floor@@GLIBC_2.0'
/usr/bin/ld: note: 'floor@@GLIBC_2.0' is defined in DSO /usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libm.so so try adding it to the linker command line
/usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libm.so: could not read symbols: Invalid operation


Can you kindly consider to remove LDFLAGS from debian/rules and apply the following patch, that adds LIBS="-lm -ldl" to configure.ac.

Thanks in advance. 

Leo.
