>From OFTC's #gcc channel, just now:
<tschwinge> Is that one known? Bootstrapping a toolchain for
arm-none-linux-gnueabi.
<tschwinge> checking for C compiler default output file name...
<tschwinge> configure: error: in

<tschwinge> configure: error: C compiler cannot create executables
<tschwinge> See `config.log' for more details.

<apinski> semi
<apinski> how are you configuring?
<apinski> and what does config.log say inside that directory?

<tschwinge> apinski: Do you want the whold configure line or something
specific?
<apinski> the whole configure line
<apinski> mainly is this a C only one?
<jakub> apinski: why should it matter? There is nothing fortran specific
on libquadmath (or, at least, there should not be)
<tschwinge> --enable-languages=c,lto
<tschwinge> apinski: http://pastebin.com/46Lys5aF
<apinski> tschwinge: use --disable-libquadmath
<jakub> it surprises me that we try to build libquadmath for arm, which
doesn't have __float128
<apinski> only x86 and ia64 have that, right?
<jakub> apinski: yeah, i?86, x86_64 and ia64
<tschwinge> apinski: Thanks you; that helps.
Here's the config.status line again; for reference when the pastebin is
