Gerald Pfeifer e526b95449 Explicitly include the GCC run time directory in LDFLAGS. This should
not be necessary when linking with GCC, but that's not the only way the
link process can be invoked.

# bsd.gcc.mk - Support for smarter USE_GCC usage.
#
# Created by: Edwin Groothuis <edwin@freebsd.org>
#
# To request the use of a current version of GCC, specify USE_GCC=yes in
# your port/system configuration. This is the preferred use of USE_GCC.
# It defines a canonical, default version of GCC. The same version of
# GCC is also implied by USE_FORTRAN=yes.
#
# USE_GCC=any is similar, except that it also accepts the old GCC 4.2-
# based system compiler in older versions of FreeBSD.
#
# If your port needs a specific (minimum) version of GCC, you can easily
# specify that with a USE_GCC= statement. Unless absolutely necessary
# do so by specifying USE_GCC=X.Y+ which requests at least GCC version
# X.Y. To request a specific version omit the trailing + sign.
#
# Use of a Fortran compiler is declared by the USE_FORTRAN knob, not
# USE_GCC.
#
# Examples:
# USE_GCC= yes # port requires a current version of GCC
# # (4.6 as of today, subject to change).
# USE_GCC= any # port requires GCC 4.2 or later.
# USE_GCC= 4.8+ # port requires GCC 4.8 or later.
# USE_GCC= 4.8 # port requires GCC 4.8.
#
# If your port needs a Fortran compiler, please specify that with the
# USE_FORTRAN= knob. Here is the list of options for that knob:
#
# USE_FORTRAN= yes # use gfortran46 (lang/gcc46)
# USE_FORTRAN= g77 # use g77-34 (lang/gcc34)
# USE_FORTRAN= ifort # use the Intel compiler (lang/ifc)
#
# Due to object file incompatiblity between Fortran compilers, we strongly
# recommend to use only one of them on any system.
#
# If you are wondering what your port exactly does, use "make test-gcc"
# to see some debugging.
