build: fix lrint detection

The configure test puts -lm into the wrong place.

configure:16102: gcc -o conftest -lm   conftest.c  >&5
/tmp/ccZ8dPRc.o: In function `main':
conftest.c:(.text+0xd): undefined reference to `lrint'
conftest.c:(.text+0x1f): undefined reference to `lrint'
collect2: ld returned 1 exit status

"-lm" is a library, not a CFLAG.
