lpgcc including the default gcc library?

[Vadim Bendebury (вб)]

Guys, there is this line in lpgcc
(http://review.coreboot.org/gitweb?p=coreboot.git;a=blob_plain;f=payloads/lib...):

_LIBGCC=`$DEFAULT_CC $_ARCHEXTRA -print-libgcc-file-name`

why is this required? Isn't the idea that libpayload provides the
entire set of modules required by the user?

TIA,
