• Update to 2.4.2

Changelog:

• The --with-pic configure option now supports a list of comma-separated package names. This can be used to build some static libraries with PIC objects while building others with non-PIC objects.
• Initial support for Go, using the gccgo compiler.
• On Mac OS X .dylib is now tried as well as .so with lt_dlopenext().

Bug fixes:

• The generic approximation of the command line length limit (when getconf is not available) works again. Regression introduced in v2.2.6-39-g9c3d4d8.
• The bug that leaked developer tool paths into the release tarballs from ./bootstrap is fixed.
• Improved support for the Cuda Compiler Driver (nvcc) on Darwin.
• For GCC LTO support, the -fuse-linker-plugin switch is now also removed when computing compiler postdeps. Important incompatible changes:
• The undocumented hardcode_libdir_flag_spec_ld tag variable has been removed in favor of using hardcode_libdir_flag_spec with $wl set to empty. Changes in supported systems or compilers:
• Fixes for gfortran on Darwin, XL Fortran on GNU/Linux.
• Support for FreeBSD 1.x (outdated since 1994) has been removed.
