[Buildroot] mtd-utils fails to build

[Buildroot] mtd-utils fails to build

[H Hartley Sweeten]

Hello all,

I am trying to do a clean build using the current git pull of buildroot.

Everything goes as expected until trying to build mtd-utils. When trying
to build mkfs.jffs2 the build cannot find zlib.h and errors out.

It appears that a compile and assemble, but do not link (option -c), happens
first for each file followed by compile and place output into <file>
(option -o).

The problem appears to be that the -c option happens without passing the
--sysroot configuration so the compiler cannot locate the external headers.

Following is a snip of the last part of the build:

Thanks, fixed in git:

commit d5bf5f967009733da99c55febacb3fb0be686cad

    mtd-utils: fix build with external toolchain
    
    Reported by H Hartley Sweeten.
    
    Make sure we pass proper CFLAGS to mtd-utils, so builds needing --sysroot
    works (E.G. external toolchains).
