[crosstool-ng] [patch] glibc-2.9 patch for "undefined reference to `_begin'

[Nye Liu <nyet at mrv dot com>]

i have no idea why this is needed for me.

for some reason the output of

"powerpc-860-linux-gnu-gcc -nostdlib -nostartfiles -shared -Wl,-z,combreloc -Wl,-z,relro -Wl,--hash-style=both -Wl,-z,defs -Wl,--verbose"

isn't doing the right thing with respect to generating the
". = 0 + SIZEOF_HEADERS;" line.

Not sure what other targets this affects.

Anybody else see this?
