Require a good assembler on ELF targets and just enable this by default for them without trying a configure test that won't work for cross compilation (AC_RUN_IFELSE is bad). The toplevel config/elf.m4 provides a good notion of what is or is not ELF (if there are problems, we can fix that file). Only a handful of targets support non-GNU assemblers; for the vast bulk of targets we should assume a not-too-old GNU assembler. That way, the configure test can be used to cause a configure-time error if the assembler is defective and it doesn't matter that the test is late. -- Joseph S. Myers jos...@codesourcery.com
