The use of -nostdlib and -nodefaultlibs disables the processing of
LIB_SPEC (%L) as specified by LINK_COMMAND_SPEC and thus disables the
default linker script for RTEMS. Move the linker script to
STARTFILE_SPEC which is controlled by -nostdlib and -nostartfiles. This
fits better since the linker script defines the platform start file
provided by the board support package in RTEMS.
gcc/
* config/rtems.h (STARTFILE_SPEC): Remove nostdlib and
nostartfiles handling since this is already done by
LINK_COMMAND_SPEC. Evaluate qnolinkcmds.
(ENDFILE_SPEC): Remove nostdlib and nostartfiles handling since this
is already done by LINK_COMMAND_SPEC.
(LIB_SPECS): Remove nostdlib and nodefaultlibs handling since
this is already done by LINK_COMMAND_SPEC. Remove qnolinkcmds
evaluation.
