gdb.dwarf2/dw2-dir-file-name.exp fails to build using Clang because the generated assembly language contains .ascii directives with more than one string literal. gdb.dwarf2/dw2-restore.exp fails to build using Clang because it contains .func and .endfunc directives. This commit causes Clang to invoke the system assembler to assemble the relevant files. gdb/testsuite/ChangeLog: * gdb.dwarf2/dw2-dir-file-name.exp: Use system assembler when compiling with clang. * gdb.dwarf2/dw2-restore.exp: Likewise
