Subject: external-toolchain: adjust check for uClibc static toolchains
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=090d486441e6ee1898a6a27f8827076464cf2110;p=buildroot.git

external-toolchain: adjust check for uClibc static toolchains

The current check for uClibc toolchain was verifying that a
ld-uClibc.so dynamic loader was present. However, with static-only
uClibc toolchains, this does not work. Instead, we check for an
uClibc-specific header file in the sysroot.
