[Question]Remove $BUILDDIR from gcc -v

[Bian, Naimeng]

Hi,

Any suggestion to remove the "$BUILDDIR" from "gcc -v".  
Maybe the building option such as --with-libtool-sysroot is unnecessary 
for toolchain. Thanks a million!

These options are required. Why do you want to remove them?

[Bian, Naimeng]

Thanks for your answer.

Removing these options is not my purpose, i just want to hide the $BUILDDIR
such like following in my sdk.

- --with-mpfr=$BUILDDIR/tmp/sysroots/x86_64-nativesdk-pokysdk-linux
+ --with-mpfr=../../ tmp/sysroots/x86_64-nativesdk-pokysdk-linux

Thanks for your answer.

Well, maybe it's a strange case,  but any suggestion it's helpful to me. ^_^
(I don't think there are some bugs of upstream's poky)

Of course, we can set BUILDDIR to a safe path such as /workspace,
but setting BUILDDIR to a secret path caused by a miss operation
will make a leakage of secret.

So, is there a method to change BUILDDIR to a relative path not a absolute path.
Looks like it's not easy. ^_^

Thats quite interesting. Why cant you then build in a directory thats
not so _secret_

I hate to break it to you but there are plenty of other ways the build
path can end up in the resulting binaries, even through things like
debug symbols/information. I'd suggest not putting "secret" information
in the build paths.
