- Trampolines or fixups for veneers provide long jump support for instruciton sets that implement short relative address branches. The linker provides trampolines when creating a static image. This patch adds trampoline support to libdl and the ARM architecture. - The dl09 test requires enough memory so modules are outside the relative branch instruction ranges for the architecture. Updates #3685
