Only indirectly.

ctypes.util.find_library()[1] uses dlltool from binutils to derive the
name of the DLL from the given import library name. This might sound
odd, but on ELF platforms gcc is also a requirement, as a small program
is compiled and linked just in order to figure out the SONAME of a given
library name.
The binutils package includes both the programs and the (static) libbfd,
libiberty, and libopcodes libraries; it is for those that libintl-devel
is a dependency of binutils. Perhaps we could consider splitting out
these libraries and their headers into a separate package
(libbfd-devel?) to avoid this.
