--host=x86_64-netbsd:
$ ../configure \
--build=x86_64-pc-linux-gnu \
--host=x86_64--netbsd \
CPPFLAGS="--sysroot=/netbsd-sysroot" \
CC=x86_64--netbsd-gcc CFLAGS="--sysroot=/netbsd-sysroot" \
CXX=x86_64--netbsd-g++ CXXFLAGS="--sysroot=/netbsd-sysroot" \
LDFLAGS="--sysroot=/netbsd-sysroot -static" \
;
$ make all-libiberty
...
../../libiberty/cp-demangle.c:119:11: fatal error: alloca.h: No such file
or directory
$ grep HAVE_ALLOCA_H libiberty/config.h
#define HAVE_ALLOCA_H 1 // incorrect on NetBSD
