    Merge branch 'ada'
    Merge ada branch to fix compile test flags.

commit 7dd28b93962f25cd42e908f24eee93e1d22de0a8

    target: Wrap linker flags into `-largs'/`-margs' for Ada
    
    Unrecognized `gnatmake' switches are not implicitly passed on to the
    linker, so just pasting board `ldflags' and any other linker flags
    verbatim into `add_flags' to use for the invocation line of `gnatmake'
    will make them ignored at best.
    
    For example in a GCC test environment that has:
    
    set_board_info ldflags 
"-Wl,-dynamic-linker,.../sysroot/lib/ld-linux-riscv64-lp64d.so.1 
-Wl,-rpath,.../sysroot/lib64/lp64d -Wl,-rpath,.../sysroot/usr/lib64/lp64d"
    
    so that sysroot paths are correctly embedded with the binaries linked
    for use with the dynamic loader and shared library dependencies, the
    setting will be ignored for the GNAT test suite making all the execution
    tests fail, e.g.:
    
    PASS: gnat.dg/abstract_with_anonymous_result.adb (test for excess errors)
    spawn qemu-riscv64 ./abstract_with_anonymous_result.exe
    /lib/ld-linux-riscv64-lp64d.so.1: No such file or directory
    FAIL: gnat.dg/abstract_with_anonymous_result.adb execution test
    
    For `gnatmake' to pass switches on to the linker the `-largs' switch has
    to be used, which affects all the switches that follow until a switch is
    seen that changes the selection, like `-margs', which resets to the
    initial state of the switch interpretation machine.
    
    Wrap linker flags into `-largs'/`-margs' for Ada then, carefully
    preserving the place these flags are placed at within `add_flags', as
    surely someone will have depended on that, correcting test failures like
    above:
    
    PASS: gnat.dg/abstract_with_anonymous_result.adb (test for excess errors)
    spawn qemu-riscv64 ./abstract_with_anonymous_result.exe
    PASS: gnat.dg/abstract_with_anonymous_result.adb execution test
    
    Pass multilib flags both to the compiler and to the linker as both build
    stages interpret them.
    
    Update the testsuite accordingly.
    
        * lib/target.exp (default_target_compile): Wrap linker flags into
        `-largs'/`-margs' for Ada.
        * testsuite/runtest.libs/target.test (compile_test): Update
        accordingly.
