Fedora link issue

The next version of Fedora enforces strict linking requirements. This
has revealed that ictrans needs to get linked with -lm:

gcc -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386
-mtune=generic -fasynchronous-unwind-tables -fPIC -o ictrans main.o
../../../.././ncarview/src/lib/libictrans/libictrans.o

../../../.././ncarview/src/lib/libcgm/libcgm.a(meta_edit.o): In function
`CGM_initMetaEdit':
/builddir/build/BUILD/ncl_ncarg-5.1.1/ncarview/src/lib/libcgm/meta_edit.c:1043:
warning: the use of `mktemp' is dangerous, better use `mkstemp'
/usr/bin/ld: ../../../.././ncarview/src/lib/libctrans/libctrans.o:
undefined reference to symbol 'sqrt@@GLIBC_2.0'
/usr/bin/ld: note: 'sqrt@@GLIBC_2.0' is defined in DSO /lib/libm.so.6 so
try adding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation

I've used the following patch, but I'm sure there is a better way:
