Pass LDFLAGS (which will contain -static) to fix the following tmon
static build failure with uclibc:

/home/autobuild/autobuild/instance-3/output-1/host/bin/x86_64-buildroot-linux-uclibc-gcc -O3 -Wall -Wshadow -W -Wformat -Wimplicit-function-declaration -Wimplicit-int  -D VERSION=\"1.0\"   tmon.o tui.o sysfs.o pid.o  -o tmon -lm -lpthread -lpanel -lncurses
