LinuxPPC: gccinstlib.pl and linker script

[Pavel Janík <Pa...@Janik.cz>]

Hi,

on my Linux/PPC box (Debian 6.0.5): gcc --print-file-name libgcc_s.so prints:

/usr/lib/gcc/powerpc-linux-gnu/4.4.5/libgcc_s.so

This file is a linker script:

/* GNU ld script
...

not a real ELF library. This breaks the expectation of the gccinstlib.pl script.

To workaround this, I have changed my makefile.mk this way:

Index: external/gcc3_specific/makefile.mk

 .ENDIF
 .ENDIF 

What do you think about this change? Who knows gcc/linker more than me?
