[Qemu-devel] [PATCH v1] roms/ipxe: use configured compiler for ipxe

[Olaf Hering]

configure allows to run a dedicated compiler binary, which is stored in
CC and HOST_CC variables, and overrides the default 'cc' command.

This command however is not used when building ipxe from source.
"make -C roms pxerom" invokes the buildsystem of ipxe.git, which has the
command "gcc" hardcoded. That binary may not be suitable to build ipxe.
Reuse the same compiler command that is used to build qemu by specifying
CC and HOST_CC as make commandline option to override the built-in
defaults of ipxe.
