 Fix build system:
 
 - ksh does not currently build on AIX or QNX.
-- On NetBSD 9.0, the build fails if /bin/sh is used as $SHELL (the default)
-  as iffe writes line numbers directly into generated header files. The cause
-  needs to be investigated. It could be a regression in NetBSD 9.0 sh.
-  Workaround: bin/package make SHELL=/some/other/shell
 - Reimport the removed nmake. It is necessary for changes in Makefiles
   to take effect. The machine-generated Mamfiles are now used as a fallback,
   but they are not meant to be edited by hand.
