Apply dirname to the first word of CXX
...in case it contains addtional arguments like -fsized-deallocation besides the
compiler's pathname, which would have caused failures like
basename: extra operand '-fsized-deallocation'
Try 'basename --help' for more information.
dirname: missing operand
Try 'dirname --help' for more information.
dirname: missing operand
Try 'dirname --help' for more information.
(printf reuses the format operand to satisfy all argument operands, so that \n |
head hack is needed to get just the first one, assuming that CXX did not contain
any carefully crafted escape sequences inside that first argument that would
expand to a newline when printing. Also, this does not cater for leading
var=value or (even more far-fetched) redirection words in CXX, but the original
code did not, either.)
