>Description:
Since revisions 1.10 and 1.11 of src/gnu/lib/libgcc4/Makefile.inc were
committed, -current builds of the hp700 port have been failing like so:

do-gnu-lib-libgcc4 ===> .
dependall ===> gnu/lib/libgcc4
dependall ===> gnu/lib/libgcc4/libgcc
dependall ===> gnu/lib/libgcc4/libgcc_eh
nbmake: nbmake: don't know how to make fptr.c. Stop
--- dependall-libgcc ---
*** [dependall-libgcc] Error code 2
A failure has been detected in another branch of the parallel make

>How-To-Repeat:
Try compiling the hp700 port.

>Fix:
Following from lukem@'s changes for m68k builds, this patch fixes the
problem for me:
