libdl: Add support for trampolines
- 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
