with structuredAttrs lists will be bash arrays which cannot be exported
which will be a issue with some patches and some wrappers like cc-wrapper
this makes it clearer that NIX_CFLAGS_COMPILE must be a string as lists
in env cause a eval failure
Without the change build fails on `ncurses-6.3` as:
oping.c:1601:38: error: too many arguments for format [-Werror=format-extra-args]
1601 | HOST_PRINTF ("%zu bytes from %s (%s): icmp_seq=%u ttl=%i ",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Without the fix build on ncurses-6.3 fails as:
oping.c:1128:25: error: format not a string literal and no format arguments [-Werror=format-security]
1128 | mvwprintw (ctx->window, /* y = */ 3, /* x = */ x + 2, symbol);
| ^~~~~~~~~
According to NEWS, the changes are in the command line tools, not the
library, so I think dependees (only collectd) will work fine.

liboping is a C library to generate ICMP echo requests, better known as
"ping packets". It is intended for use in network monitoring
applications or applications that would otherwise need to fork ping(1)
frequently.
