Details:

Hi, discovered a bug on a big-endian MIPS setup where posix_spawn(), added in
make-4.3, doesn't appear to work right.  When make tries to do operations like
executing files, changing directories, calling other programs (e.g., sed),
etc, it fails.  Errors range from "operation not permitted" to "cd: <dir>: not
a directory", to "permission denied".  Tested on both O32 ABI and N32 ABI. 
Cannot test little-endian due to lack of hardware.

I eventually worked out that rebuilding make-4.3 with --disable-posix-spawn
results in a working build.  So I am not sure if make's use of posix_spawn is
broken, or if the MIPS implementation in glibc is broken.
