This is a Debian bug, not a pitivi or meson bug. Here's how you
reproduce it:
---
$ export MAKE="ninja -v"
$ echo "int main(void) { return 0; }" > test.c
$ cc test.c -o test -flto=auto
ninja: error: /tmp/ccCz1Mkh.mk:1: lexing error
lto-wrapper: fatal error: ninja returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
collect2: error: ld returned 1 exit status
---
So there's some linker / lto script that uses $MAKE and expects it to
actually be a make implementation. Which is a reasonable expectation,
but debian/rules is setting MAKE to ninja for Meson recipes.
I can reproduce the same issue on Fedora, so it's not a Debian-specific
linker / lto script.
