[PATCH] mk: use extra cflags when linking libs with a compiler

[PATCH] mk: use extra cflags when linking libs with a compiler

[Gage Eads]

When using the compiler to link libraries, include EXTRA_CFLAGS. This is
needed when cross-compiling to pass --sysroot, for example. GCC
cross-compilers built with Yocto don't use the --with-sysroot option,
making it necessary to pass the --sysroot command-line option.

This is the same solution as in commit e8fbb6d9cfd9 ("mk: use extra cflags
when linking with compiler"), but applied to libs instead of apps.

You forgot the Signed-off-by line.

[Eads, Gage]

Sure, will fix that now. I was just waiting for any other feedback to include in a v2.

[PATCH v2] mk: use extra cflags when linking libs with a compiler

[Gage Eads]

When using the compiler to link libraries, include EXTRA_CFLAGS. This is
needed when cross-compiling to pass --sysroot, for example. GCC
cross-compilers built with Yocto don't use the --with-sysroot option,
making it necessary to pass the --sysroot command-line option.

This is the same solution as in commit e8fbb6d9cfd9 ("mk: use extra cflags
when linking with compiler"), but applied to libs instead of apps.

Applied, thanks
