I've applied to next. However, there was still a bug.

The opposite of:

  BR2_TOOLCHAIN_USES_UCLIBC || BR2_TOOLCHAIN_USES_GLIBC

is not:

  !BR2_TOOLCHAIN_USES_UCLIBC || !BR2_TOOLCHAIN_USES_GLIBC

Indeed, with this expression, if glibc is used,
BR2_TOOLCHAIN_USES_UCLIBC is false,
therefore !BR2_TOOLCHAIN_USES_UCLIBC is true, and the comment is
displayed... even if you're using glibc, which is a valid configuration!

The proper expression is:

  !(BR2_TOOLCHAIN_USES_UCLIBC || BR2_TOOLCHAIN_USES_GLIBC)

In this case, if you use glibc, BR2_TOOLCHAIN_USES_UCLIBC ||
BR2_TOOLCHAIN_USES_GLIBC is true, and therefore the overall expression
is false, and the comment is not displayed.

Best regards,

Thomas
