Downloads the source archive for <pkg-name> needed by coreboot's
|
|
crossgcc toolchain. The package version and digest are found in
|
|
coreboot-dir. The package is downloaded to <pkgs-dir>, then placed in
|
|
the coreboot directory.

|
|
Uses fetch_source_archive.sh, so mirrors are used and WGET can override
|
|
the path to wget.
