Glibc upstream has marked their bug as fixed, and I can confirm that make-4.3 works on MIPS after rebuilding glibc with the patches.  This bug can be resolved.  Thanks!

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.
