> We are trying to cross compile stdcxx library. The problem we are facing
> is that there is no way of telling stdcxx build system, that we don't
> want to run configuration files created by configuration step by build
> system directly on a host system (through a shell).
> For instance, this command (taken from log):
> ./UNISTD_DECL
> invoked during configuration process runs natively the executable through
> a shell.
> However we want to be able to run it on a emulator like this:
> <path to our emulator> UNISTD_DECL
> This command will run the UNISTD_DECL through an emulator.
> The patch we are proposing, is to introduce a new Makefile variable, called
> EXEC_RUNNER, which allows us to do it.
> EXEC_RUNNER defaults to "/usr/bin/sh -c". so it does not interfere with
> the rest of build process (at least on Unix/MSys/Cygwin environment,
> pure Win32 platform has completely separate build system).
> Patch is against `trunk'.
