[Bug 1348945] [NEW] -lsensors doesn't link to libsensors

[B. Joshua Rosen]

Public bug reported:

I have libsensors4-dev installed however gcc is getting link errors,

gcc -O2 -Wuninitialized -Wall -D_FORTIFY_SOURCE=2 -Wformat -Wno-multichar -Wreturn-type -Wswitch -Wunused-variable -g  -lm -pthread -lsensors	 -o sys_basher sys_main.o sys_utils.o sys_disk.o sys_kernel.o sys_fp.o sys_int.o sys_mem.o lin_utils.o -lsensors sys_sensors3.o

collect2: error: ld returned 1 exit status

I'm trying to build by sys_basher program for Ubuntu. I have it in the
Fedora and EPEL repositories for RPM systems where it builds without any
errors or warnings.
